3、d of synthetic resin materials for vehicles. (Spec. No: GMW3116) 3. APPLICATION 3.1. Group 1: Raw materials of high melt flow injection mold which have excellent dimensional stability and molding ability. 3.2. Group 2: Heat resistance raw materials having excellent dimensional stability and molding

4、ability 3.3. Group 3: Raw materials of high melt flow injection mold which have excellent dimensional stability, molding ability and especially chemical resistance. Notice to Use Parts which were molded using this specification material can be damaged as contacted by foam, rubber, seal, PVC products

5、 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 necessary, surface treatment methods such as painting with clear coat, coated gold, etc must be used

6、 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 Adipate), etc 4.
