9、. 03. 26 VERSION: 6 GM DAEWOO Auto & Technology 5.3. Group 3: High heat and impact resistance raw materials which have heat deflection temperature of 100 or higher. 5.3.1. Type 1: Raw materials which the heat resistance has been improved by adding of PMI heat-resistance material and the impact-resis
10、tance properties has been improved by using base material with High-rubber ABS. Ex) I/P Center Molding 5.3.2. Type 2: Raw materials which the heat resistance has been improved by adding of PMI heat-resistance material and the impact-resistance and mechanical properties have been improved by adjustin
11、g of Polycarbonate content. Ex) I/P Center Molding, I/P LWR type Notice to Use Parts which were molded using 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 plast
12、icizers 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 to prevent chemical crack by plasticizers migration. # Phthalic Acid Ester plasticizer: DOP(Di-Octy
