Elastomere - characteristics of combustibility, chemical resistance and ingredients

¹⁾ Minus values in temperature range apply only to parts in idle state without impact stress.

²⁾ The following details should be regarded as guidelines only. Any more definite information can only be given with reference to the particular application in hand. For example, a precision part may fail simply on account of a slight change in volume, or aggressive media may in fact be usable as cleansing agent if only briefly in contact with the material in question.
A - Very good, chemical resistance. Constant action of medium causes no damage to plastic within a period of 30 days. The plastic may remain resistant over a period of several years.
B - Good to limited chemical resistance. Constant action of medium may cause slight damage within a period of 7 to 30 days, this damage some times being reversible (swelling, softening, reduction in mechanical strength, discolouration).
C - Low chemical resistance. Unsuitable for subjection to constant action of medium. Damage may occur immediately (reduction in mechanical strength, deformation, discolouration, cracks, dissolution).
