Features & Benefits

Core Competitive Advantages

• Outstanding Impact Resistance A notched Izod impact strength of 114 J/m ensures that products are less prone to cracking when subjected to external impacts or drops, making it especially suitable for consumer products and appliance applications requiring high durability.

• Excellent Processing Fluidity Precise control of the melt flow rate at 3.3 g/10min ensures stable fluidity during molding processes such as injection molding and extrusion, facilitating the production of complex geometries and thin-walled parts while reducing mold wear.

• Superior Rigidity and Strength A flexural modulus of 2157 MPa and tensile modulus of 1961 MPa endow the product with outstanding dimensional stability and structural rigidity, enabling it to maintain its shape long-term in load-bearing applications.

• Balanced Bending Characteristics and Elasticity A balanced design featuring a flexural strength of 58 MPa and a tensile strain of 39% provides the material with both sufficient hardness to support structural applications and a degree of flexibility to absorb impact energy, thereby extending product service life.

• Broad Thermal Stability A heat deflection temperature of 93 °C and a Vicat softening temperature of 103 °C meet the operating temperature requirements of conventional home appliances and consumer electronics, adapting to changing thermal environments during daily use.

• Excellent Surface Quality and Colorability The product features uniform pellets that are easy to color and surface-treat, enabling the production of end products with high aesthetic appeal that meet modern consumer demands for appearance.

• Cost-Effectiveness Advantage As a mature engineering plastic, Formosa 825G HIPS achieves an optimal balance between performance and cost, offering significant price competitiveness compared to high-end engineering plastics and making it suitable for large-scale industrial production.

Applications

• Home Appliances & Consumer Electronics: Refrigerator, washing machine, and television housings; remote controls, keyboards, and other small electronic products and control panels.

• Automotive Industry: Automotive interior components, door handles, vent covers, and other parts.

• Medical Devices & Daily Commodities: Medical equipment housings, oral care products (toothbrush handles, gargle cups), and cosmetic containers.

• Consumer Goods & Packaging: Children’s toys, daily plastic products (trash cans, storage boxes), and rigid packaging boxes and shipping containers.

Frequently Asked Questions (FAQs)

Q1: Does Formosa 825G HIPS require drying treatment prior to molding?

A: Yes. Although HIPS does not absorb moisture as strongly as PA or PET, it still requires drying to achieve optimal molding results. Recommended drying conditions:

• Drying Temperature: 70–80 °C

• Drying Time: 2–4 hours

• Relative Humidity: <0.1%

• Material should be fed into the molding machine immediately after drying to prevent re-absorption of moisture.

Q2: What are the differences between Formosa 825G HIPS, PMMA, and PC?

A: Main differences among the three materials:

Selection Recommendation: Choose HIPS for opaque, high-impact products, and PMMA or PC when transparency is required.

Q3: Does Formosa 825G HIPS comply with RoHS, food contact, and other certifications?

A:

• RoHS Certification: Standard HIPS typically complies with RoHS 2.0 requirements.

• Food Contact Certification: The base material can be used for food contact applications, but certification status must be confirmed for specific batches.

• Recommendation: Consult official Formosa sources for relevant certification documents (COC/TDS) prior to specialized applications.
