Frequently Asked Questions (FAQ)
-
Q: What makes the SABIC 500R-739 "flame retardant"?
A: This grade incorporates specific additives that inhibit or slow down the ignition and spread of flame, enhancing the material's performance in fire safety tests relevant to electrical applications. -
Q: Can this material be used for outdoor electrical applications?
A: Polycarbonate has good UV resistance, but for long-term outdoor use, specific UV-stabilized grades might be more suitable. The 500R-739's primary focus is flame retardancy; its outdoor performance should be evaluated based on exact requirements. -
Q: What are the typical processing conditions for injection molding this granule?
A: Processing follows general polycarbonate guidelines. Typical melt temperatures range between 280-320°C, with mold temperatures around 80-100°C. Exact settings depend on the part design and machinery. -
Q: Does it come in colors other than natural?
A: The standard supply is natural, but color customization is often possible. Please inquire about specific color requirements. -
Q: What electrical safety standards might this material help meet?
A: It can contribute to meeting flammability requirements in standards such as UL (Underwriters Laboratories) for electrical equipment, though final product certification depends on the complete design and testing. -
Q: How does its flame retardancy affect other mechanical properties?
A: Flame-retardant additives can sometimes slightly alter properties like impact strength or clarity. The SABIC 500R-739 is formulated to balance flame retardancy with maintaining key polycarbonate mechanical properties. -
Q: What is the packaging and minimum order quantity?
A: It is typically supplied in standard plastic bags (e.g., 25kg bags). Minimum order quantities are flexible and can be discussed based on your needs. -
Q: Are technical data sheets available?
A: Yes, detailed technical data sheets specifying properties like melt index, tensile strength, and flame test ratings are available upon request.
