"in the light of rising d

dustry sets extremely low 

limits for the emission of

 volatile organic compound

s (voc)," said hans-herman

sts of samples of the new 

impact-modified delrin? 30

 institute in herten, germ

any, revealed formaldehyde

 emissions of 1.0 mg/m2 an

d lower. such results are 

considerably below the lim

it of 2.0 mg/m2 set by lea

ding german oems and mean 

that the new material meet

s the world's most stringe

nt re with regar

low index (mfi190/2,16) of

 6 g/10min, delrin? 300te 

bridges the gap between de

lrin? 100t (mfi = 2), whic

h combines high viscosity 

with very high impact resi

stance, and the medium vis

delrin? 300te is considera

bly more impact resistant 

than delrin? 300pe, a prev

iously launched low-emissi

on grade that also is suit

able for use in automotive

 interiors. it achieves a 

notched impact strength at

 23°c of 18 kj/m2 (delrin?

 300pe: 11 kj/m2). at –30°

c, the notched impact stre

ngth of the new 300te grad

e is still as high as 10 k

j/m2 (300pe: 8 kj/m2).

as with all members of the

 acetal resin family from 

dupont, new delrin? 300te 

also combines high strengt

h, hardness and stiffness 

over a broad temperature r

ange with high abrasion re

sistance and a low coeffic

ient of friction, a high h

eat deflection temperature

, good electrical and diel

ectric properties and high

 dimensional stability.

kirner adds: "thanks to i

ts high-melt flow, thin-wa

lled parts with long flow 

paths — for instance the s

truts used in headrests — 

are among the principal ar

eas for developments in de

lrin? 300te. in general al

l pom grades are suitable 

for use in low-noise and l

ow-friction control and dr
