New Material
Series
The struc­ture of rat­tan is com­par­able to that of a bundle of tubes. The rat­tan palm can trans­port wa­ter up to 160 meters through its long ca­pil­lar­ies. out for space takes ad­vant­age of this nat­ur­al prop­erty for its one-of-a-kind, pat­en­ted tech­no­logy. When the ca­pil­lar­ies are in­jec­ted with vari­ous bulk­ing agents,
rat­tan is trans­formed from a
lim­ited-use wood in­to an in­nov­at­ive wood-based ma­ter­i­al of
the fu­ture.
The new ma­ter­i­al, karuun, is firmer, harder, weath­er-­res­ist­ant and even has a new char­ac­ter­-
ist­ic col­or­a­tion. karuun presents an al­tern­at­ive to oth­er more
ex­pens­ive ma­ter­i­als, with ap­plic­a­tions in mul­tiple areas.

Aside from the struc­tur­al en­hance­ments, the new treat­ment tech­no­logy also gives karuun the ad­vant­age in terms of ap­pear­ance and main­ten­ance. The char­ac­ter­ist­ic col­or­ation of karuun col­or runs throughout the pro­file of the ma­ter­i­al and cre­ates a whole new aes­thet­ic. The im­preg­na­tion of the ma­ter­i­al through ca­pil­lary in­jec­tions al­lows karuun col­or to be used as a base ma­teri­al for vari­ous semi-fin­ished products such as wick­er, ven­eer or boards.
Sur­face im­per­fec­tions can simply be sanded away and through the in­teg­ra­tion of oils and waxes in the dye it is pos­sible to both fin­ish and pro­tect the sur­face in the same pro­duc­tion step.

karuun® solid –
Combining Qualities
of Rattan and
Bentwood
 
 
 
 
 
With its im­proved ma­ter­i­al prop­er­ties karuun sol­id is com­par­able with bent­wood. A clear ad­vant­age of pro­cess­ing raw rat­tan is its high elasti­city and bend­abil­ity. These prop­er­ties al­low rat­tan to be shaped with very little force or en­ergy. For man­u­fac­tur­ing
fur­niture, however,
rat­tan’s elasti­city is a dis­ad­vant­age be­cause of the ef­fect it has on the strength and stiff­ness of the ma­ter­i­al. For ex­ample, the ex­tra struts needed to in­crease the struc­tur­al sta­bil­ity of a chair made of rat­tan de­tract from its aes­thet­ic
ap­peal.
out for space solves this prob­lem by treat­ing karuun sol­id with com­postable bulk­ing agents. In this way the nat­ur­al flex­ib­il­ity and elasti­city of rat­tan is
re­tained while at the same time lend­ing
rat­tan the strength of
a hard wood. karuun
sol­id
there­fore cre­ates new pos­sib­il­it­ies not only for fur­niture design.

karuun® proof –
Upgrading Rattan to
Weather-Resistant
 
 
 
 
 
This great step for­ward against weath­er­ing makes karuun ap­peal­ing for out­door use. Rat­tan is by nature not suited to out­door use due to its poor weath­er­ing, lead­ing the way for a dom­in­ance of plastic in the do­main of out­door fur­nish­ing. However, the hy­dro­phobic bulk­ing agent in karuun proof greatly im­proves the weath­er­ing of rat­tan so it can be used out­side. The bulk­ing agent fills the pores of the rat­tan
wood, turn­ing what would oth­er­wise be a breed­ing ground for mold and mois­ture in­to the back­bone of the ma­ter­i­al. Out­door fur­ni­ture made from karuun proof could last just as long as oth­er out­door ac­cessor­ies made
from trop­ic­al woods, without the eco­lo­gic­al con­se­quences of the de­for­est­a­tion of our rain­forests.

Future Prospects –
A Bright and Successful
Path Lies Ahead
The ma­ter­i­al im­prove­ments lent to rat­tan
by re­fine­ment are com­par­able to those of
pro­cessed bam­boo. Bam­boo has be­come an im­port­ant wood-work­ing ma­ter­i­al and is now used in areas in which it was pre­vi­ously deemed un­suit­able.
karuun has the same po­ten­tial to be­come rel­ev­ant as a new and in­nov­at­ive nat­ur­al wood ma­ter­i­al. With con­tin­ued ma­ter­i­al
re­search, the de­vel­op­ment of man­u­fac­tur­ing pro­cesses and a
de­gree of cre­ativ­ity, karuun has a bright and suc­cess­ful fu­ture ahead of it.
It is also of great im­port­ance to out for space that rat­tan once again be­comes a steady source of
in­come for the nat­ive pop­u­la­tions of the areas where it is pro­duced. Long-term re­for­est­ation pro­jects along with en­vir­on­ment­al
ini­ti­at­ives not only
con­trib­ute to rat­tan pro­duc­tion but will also lead to a sus­tain­able fu­ture.
out for space is look­ing for­ward to co­oper­a­tion with part­ners who wish to sup­port the fur­ther de­vel­op­ment of karuun as a valu­able, in­tel­li­gent and fu­tur­ist­ic
ma­ter­i­al. If we’ve awoken your in­terest please contact us via

out for space is an in­ter­disci­plin­ary team of engin­eers and de­sign­ers who share the vis­ion of com­bin­ing re­search with aes­thet­ics to cre­ate a whole new way of de­vel­op­ing and pro­du­cing products.
Pas­sion­ate about head­ing out­doors out for space is (re)dis-­
cov­er­ing nat­ur­al ma­ter­i­als, us­ing them to cre­ate in­nov­a­tion and sus­tain­ab­il­ity.
Approach and
Profile – the Rediscovery
of Rattan
At the heart of the design pro­cess is the ma­ter­i­al. In­spired by nature and tra­di­tion­al man­u­fac­tur­ing tech­niques out for space de­vel­ops in­nov­at­ive pro­duc­tion pro­cesses and products that are good not only for con­sumers but also for the en­vir­on­ment. out for space sets the bar high for qual­ity and cre­ativ­ity, from the very first steps of pro­duc­tion right through to the fi­nal in the be­lief that in today’s world trans­par­ency and sus­tain­abil­ity should be a mat­ter of course. Just as im­port­ant as the joy of de­vel­op­ing and shap­ing a new cre­ation is the so­cial re­spons­ib­il­ity that comes with it!
out for space first took the stage with the re­dis­cov­ery of nat­ur­al rat­tan. Rat­tan is a type of palm nat­ive mainly to trop­ic­al areas in Africa, Asia and Lat­in Amer­ica, which provide an ideal warm and hu­mid cli­mate.
Through vis­its to In­done­sia, out for space be­came aware of this neg­lected ma­ter­i­al
and soon de­veloped a vis­ion for re­an­im­at­ing its use.
In Asia rat­tan is tra­di­tion­ally used as a ma­ter­i­al for fur­niture and is the foun­da­tion for many pieces. With the ad­vent of ma­ter­i­als such as poly­r­at­tan, however, nat­ur­al rat­tan has sadly lost some of its former pop­ular­ity and sig­ni­fic­ance. Es­pe­cially in Europe, the prop­er­ties, pro­duc­tion pro­cesses and po­ten­tial sus­tain­ab­il­ity of the ma­ter­i­al are al­most for­got­ten today.
For out for space, however, rat­tan is a source of un­lim­ited po­ten­tial and far more uses than formerly ima­gined.
In co­oper­a­tion with
the In­nov­a­tion Cen­ter Lichten­fels and the
Uni­versity of Ap­plied Sci­ences Coburg
, out for space has de­veloped a pat­en­ted re­fin­ing pro­cess that lends rat­tan a char­ac­ter­ist­ic new col­or­a­tion and re­solves the sig­ni­fic­ant tech­nic­al dis­ad­vant­ages of raw un­pro­cessed rat­tan.
out for space first premiered ma­ter­i­al samples at the imm co­logne 2014 and was af­ter­wards in­vited by the In­done­sian Min­istry of In­dustry to the world rat­tan pro­duc­tion cen­ter in Cire­bon as well as to the In­done­sian Rat­tan In­nov­a­tion Cen­ter, PIRNas, in Palu.
Us­ing the know­ledge picked up in In­done­sia, out for space was then able to de­vel­op a ma­chine that en­ables the re­fine­ment of rat­tan in seri­al pro­duc­tion, ad­ap­ted to the loc­al and re­gion­al con­di­tions.
The name of this pro­cessed ma­ter­i­al is karuun, it opens up the use of rat­tan in pre­vi­ously in­con­ceiv­able ways. karuun car­ries the prom­ise of a
new, en­vir­on­ment­ally-friendly ma­ter­i­al for high qual­ity products.
out for space’s spon­sors in­clude the Fed­er­al Ger­man Gov­ern­ment, the Fed­er­al Min­istry for Eco­nom­ic Af­fairs and En­ergy as well as the European So­cial Fund.

Rattan – a Proven
Material with a Long
Tradition
Qualities – Benefits
and Drawbacks of
Rattan
 
Sustainability –
an Almost Forgotten
Aspect
 
 
Rat­tan or Rotan (ind.-malay) grows al­most ex­clus­ively in rain­forests and 80 % of glob­al rat­tan pro­duc­tion is in In­done­sia. The most im­port­ant genus is nat­ive to Africa and Asia and is called Cal­amus. With 374 dif­fer­ent spe­cies, Cal­amus is the most di­verse palm.
It is widely un­known that cer­tain spe­cies of rat­tan grow to a dia­met­er of 100 mil­li­meters and can reach a total length of 160 meters, mak­ing it one of the longest plants on the plan­et! Thin rat­tan called ped­dig is tra­di­tion­ally used for wick­er­work and thick­er rods are used for fur­niture frames.
The wood of the rat­tan palm is unique in its in­tern­al struc­ture. Un­like oth­er woods, the ca­pil­lar­ies of rat­tan are long single tubes which travel the length of the en­tire plant and sup­ply it with wa­ter. Due to this, rat­tan is very elast­ic when made wet and even more so when ex­posed to heat or steam. This makes fur­ther pro­cessing ef­fi­cient and gives rat­tan ad­vant­age­ous prop­er­ties such as its light weight, elasti­city and high bend­ab­il­ity.
On the oth­er hand, it isn’t pos­sible to treat the sur­face of un­pro­cessed rat­tan with con­ven­tion­al meth­ods be­cause the or­tho­sili­cic acid in its skin pre­vents ad­he­sion.
If the out­er lay­er is re­moved, sur­face treat­ment such as paint­ing and dye­ing is pos­sible, but even then the col­or will fade with time and there is only lim­ited pro­tec­tion against weath­er­ing and us­age.
This is due to the mate­ri­al’s large pores, which make it sus­cept­ible to mois­ture and mold. The elast­ic and supple wood lent to rat­tan by its poros­ity also lim­its its field of ap­plic­a­tion. Even stronger rat­tan rods with dia­met­ers of over 30 milli­meters, used as chair legs for ex­ample, need ex­tra struts to give them ad­di­tion­al sta­bil­ity.
Rat­tan grows very quickly and has sig­ni­fic­ant ad­vant­ages over oth­er types of wood. For ex­ample, rat­tan nat­ur­ally forms a sym­bi­ot­ic re­la­tion­ship with its neigh­bor­ing plants in the rain­forest, such as the cen­tur­ies old Mer­anti Tree. The rain­forest is es­sen­tial for rat­tan: this means that cul­tiv­at­ing rat­tan would pro­mote rain­forest pre­ser­va­tion or even re­for­est­a­tion as op­posed to the ex­pan­sion of mono­cul­tures in­to the rain­forest. Pur­chas­ing rat­tan products in­dir­ectly con­trib­utes to the health and pre­ser­va­tion our world’s rain­forests.
