All About HIPS: Material Introduction & Comparison with PP and ABS

All About HIPS: Material Introduction & Comparison with PP and ABS

1. What is HIPS (High Impact Polystyrene)?

HIPS stands for High Impact Polystyrene, a modified amorphous thermoplastic derived from general-purpose polystyrene (GPPS). Pure GPPS is extremely brittle and cracks easily upon slight collision. Manufacturers add butadiene rubber particles into polystyrene resin to absorb impact energy, which greatly upgrades its anti-drop performance and creates HIPS.

Core Features of HIPS

1.Appearance & Color Matching

Natural HIPS is matte milky white, fully opaque without transparency. It supports stable solid color tinting (black, orange, green, pink etc.) and delivers uniform coloring for injection-molded products like plastic cups, toy shells and packaging containers.

2.Excellent Printing Performance

No surface corona treatment is required before screen printing, pad printing or hot stamping. Ink adheres firmly to HIPS surfaces, making it ideal for products with custom brand logos and patterns.

3.Great Molding Efficiency

HIPS melts smoothly during injection molding, with low shrinkage rate after cooling. It shortens production cycles and fits mass production on standard injection machines, reducing defective rates for thin-wall daily products.

4.Cost Advantage

HIPS is cheaper than both PP and ABS raw materials, delivering obvious cost savings for mass promotional items, disposable cold-drink cups and low-to-medium-end plastic gifts.

5.Food-Grade Availability

Food-contact HIPS grades pass FDA and LFGB certifications, safe for holding cold beverages, yogurt and room-temperature food.

6.Limitations of HIPS

Max long-term service temperature: ≤60°C. It deforms under hot water, microwave or dishwasher heat, only suitable for cold/room-temperature use.

Poor oil resistance: Long-time contact with grease causes whitening and surface corrosion.

Brittle in low-temperature environments; not recommended for outdoor winter use.

Low wear resistance compared to ABS; scratches form easily under hard friction PMC.

3. Suitable Scenarios for Each Material

HIPS Best Fits

Short-cycle promotional gifts, disposable cold beverage cups, seasonal toy shells and retail packaging boxes where low cost and custom printing are top priorities, and no hot-liquid contact is needed.

PP Best Fits

Reusable daily tableware, microwavable food containers, water bottles and kitchen tools that need heat resistance and repeated washing.

ABS Best Fits

Mid-to-high-end durable products requiring long service life, heavy impact resistance and stable performance in variable temperatures, such as appliance shells, premium kitchenware and travel suitcases.

4. Quick Material Selection Guide

Choose HIPS if you need low unit cost, mass custom printing, and only cold/room-temperature application.

Choose PP if your product needs to hold hot liquid, go into dishwashers or microwaves.

Choose ABS if you need durable, scratch-resistant goods that work reliably in both hot and cold environments.
