SCOPE This specification defines general requirements for raw materials of extrusion molding acrylonitrile-butadiene-styrene copolymer applied to interior and exterior parts of a vehicle. 2. MATERIAL INDICAT
3、ION Material indication: ABS Detailed contents shall conform to the indication method of synthetic resin materials for vehicles.(Spec. No: GMW3116) 3. APPLICATION 3.1. Group 1: Medium heat resistance raw materials which have heat deflection temperature of 90 min. 3.2. Group 2: Heat resistance raw ma
4、terials which have heat deflection temperature of 95 min. 3.3. Group 3: High heat resistance raw materials which have heat deflection temperature of 100 min. 3.4. Group 4: Super heat resistance raw materials which have heat deflection temperature of 105 min. Notice to Use Parts which were molded usi
5、ng this specification material can be damaged as contacted by foam, rubber, seal, PVC products with plasticizer such as DOP, DOA, etc., because contacted parts can be chemically cracked by plasticizers migration. So the use of product must be avoided in case of contact. But, if the contact is necess
6、ary, surface treatment methods such as painting with clear coat, coated gold, etc must be used to prevent chemical crack by plasticizers migration. # Phthalic Acid Ester plasticizer: DOP(Di-Octyl Phathalate), DBP(Di -Butyl Phathalate), etc # Aliphatic Acid Ester plasticizer: DOA(Di 2-ethyl- hexyl Ad
