Features & Benefits

• Outstanding Impact Resistance: Backed by a scientifically optimized rubber-phase dispersed structure, this grade features exceptional notched Izod impact strength (125 J/m), effectively absorbing external impacts and reducing the risk of breakage during assembly and use.

• Good Processing Fluidity: With a melt flow rate (MFR) of 4.8 g/10 min (200℃/5Kg), it exhibits superior melt flow velocity, making it highly suitable for manufacturing complex, thin-walled, or large-scale injection-molded parts.

• Excellent Dimensional Stability: The material has low molding shrinkage, ensuring that products are less prone to severe warping and deformation during cooling and subsequent use, which guarantees assembly tolerances for industrial components.

• Balanced Comprehensive Thermal Properties: Featuring a heat deflection temperature of up to 80℃ (1.82MPa) and a Vicat softening point of up to 90℃, it satisfies the thermal stability requirements of most conventional household appliances and electronic devices under daily operating environments.

• High Cost-Effectiveness and Environmental Compliance: As a general-purpose thermoplastic engineering modified plastic, its overall cost possesses strong market competitiveness while complying with mainstream international environmental and export compliance standards.

Applications

• Home Appliance Housings & Internal Components: Widely used to manufacture television back covers, air conditioner panels, washing machine structural parts, as well as internal storage boxes and trays for refrigerators.

• Consumer Electronics: Suitable for office automation equipment housings such as printers and copiers, as well as various structural support parts.

• Toy Manufacturing: Frequently used to produce various children’s toys, model casings, and educational assembly blocks, highly favored for its good toughness and safety.

• Daily Goods & Packaging: Can be used to manufacture cosmetic cases, disposable daily goods housings, and various light industrial turnover boxes and containers.

Frequently Asked Questions (FAQs)

Q1: Is strict drying treatment required before processing Shanghai Secco HIPS 622?

A1: HIPS resin inherently has low moisture absorption and can typically be loaded directly into the injection molding machine after opening under normal workshop environments. However, if the raw material has been exposed to the air for a prolonged period or kept in a high-humidity environment, it is recommended to pre-treat it at 70–80°C for 2–3 hours of drying prior to injection molding to thoroughly prevent surface silver streaks or bubbles on the finished parts.

Q2: What are the performance and application differences between HIPS 622 and general-purpose GPPS (General-Purpose Polystyrene)?

A2: General GPPS (such as GPPS 500) features high transparency and rigidity, but is very brittle and prone to shattering; whereas Shanghai Secco HIPS 622 is a high-impact polystyrene modified through the incorporation of rubber, sacrificing some transparency (appearing opaque milky-white or dyeable) in exchange for significant impact toughness and ductility. Therefore, it is better suited for housings and structural parts subjected to certain mechanical stresses.

Q3: Does this material meet RoHS and other international trade compliance requirements?

A3: Yes. Shanghai Secco HIPS 622 complies with the European Union’s RoHS directive and related environmental regulatory requirements.
