Features & Benefit

• High Impact and Toughness Balance: Modified through the introduction of a rubber phase, it features outstanding impact resistance (such as a notched Charpy impact strength of up to 130 kJ/m² at -30℃), effectively preventing brittle fracture of products during drops or under pressure.

• Excellent Processing Flowability: With a moderate melt flow rate (MFR), it exhibits superior injection molding processing performance, easily filling complex molds and shortening production cycles.

• Good Dimensional Stability: Features a low molding shrinkage rate (0.4% to 0.7%), ensuring high dimensional consistency for mass-produced products and reducing warpage deformation.

• Superior Surface Gloss and Appearance: Endows final products with a delicate and smooth surface texture, meeting the high aesthetic standards of home appliances and consumer electronics.

• Combined Flame Retardancy and Electrical Insulation: Features a UL 94 94HB flammability rating alongside excellent volume resistivity (> 10^14 ohms·cm), making it suitable for electrical and electronic insulation component applications.

Applications

• Home Appliance Casings: Widely used for manufacturing indoor air conditioner panels, washing machine components, television structural parts, and microwave oven housings.

• Consumer Electronics: Suitable for printer and copier housings, router bodies, audio equipment enclosures, and monitor bezels.

• Daily Use & Office Supplies: Commonly utilized to produce various plastic storage boxes, file baskets, toy housings, clothes hangers, and bathroom accessories.

• Packaging & Containers: Applicable for producing thin-walled packaging boxes and various industrial logistics trays that require specific toughness.

FAQs

Q1: Does Yangzi BASF 476L require drying pretreatment prior to injection molding?

A1: HIPS materials have extremely low water absorption (< 0.1%). When packaging remains intact and well-sealed in a dry environment, drying is generally unnecessary before direct use. However, if the raw material is exposed to humid environments for an extended period, hot-air drying at 70–80 ℃ for 1–2 hours is recommended to avoid bubbles or silver streaks on the product surface.

Q2: Does this grade possess relevant environmental and compliance certifications (such as RoHS or UL certification)?

A2: Yes. The material complies with the RoHS directive and relevant environmental regulations concerning restricted substances, and its flammability performance reaches the UL 94 94HB standard. Specific compliance certificates or third-party testing reports can be requested from the supplier.

Q3: What are the main performance differences between Yangzi BASF 476L and general-purpose polystyrene (GPPS)?

A3: GPPS offers good rigidity and high transparency but is brittle in texture. In contrast, 476L, as a high-impact polystyrene (HIPS), significantly enhances impact strength and toughness via rubber modification (e.g., an elongation at break of 50%). While its appearance shifts to an opaque milky-white, it holds a definitive advantage in structural applications that must withstand mechanical stress and drop impacts.
