Engineered for Impact and Processing Excellence

Transform your manufacturing capabilities with our High Impact Polystyrene, where exceptional impact resistance meets superior processing characteristics in a cost-effective solution.

Understanding HIPS (High Impact Polystyrene)

High Impact Polystyrene represents a remarkable achievement in polymer engineering, created through the precise grafting of polybutadiene rubber within a polystyrene matrix. This unique molecular architecture creates a two-phase system where rubber particles are uniformly distributed throughout the rigid polystyrene backbone. Imagine a microscopic network where countless rubber particles act like tiny shock absorbers, dispersed perfectly within the crystal-clear polystyrene structure, providing both strength and processability.

HIPS Classifications

General Purpose Grades

Our general-purpose grades feature MFI ranges from 3 to 8 g/10min, delivering balanced performance for everyday applications. These grades serve as the foundation of our HIPS portfolio, offering excellent processability and consistent quality. The careful balance of rubber content ensures good impact strength while maintaining the superior flow characteristics that HIPS is known for.

High Flow Grades

Engineered specifically for thin-wall applications, our high-flow grades showcase MFI ranges from 8 to 12 g/10min. These grades excel in fast-cycle injection molding applications where quick mold filling is crucial. Despite their enhanced flow properties, they maintain respectable impact strength, making them ideal for disposable packaging and thin-walled containers.

Extra High Impact Grades

Our premium impact-resistant portfolio features carefully optimized rubber content with MFI ranges from 2 to 5 g/10min. These grades deliver exceptional toughness for demanding applications, achieving impact strengths up to 40% higher than general-purpose grades. The increased rubber content is precisely controlled to maintain good processability while maximizing impact resistance.

Sheet Extrusion Grades

Specially formulated for sheet manufacturing, these grades offer MFI ranges from 4 to 6 g/10min. Their unique formulation ensures excellent gauge control and surface finish in sheet extrusion processes. These grades combine good impact strength with superior thermoforming characteristics, making them perfect for packaging applications requiring both durability and aesthetic appeal.

Applications in Modern Industry

In the packaging industry, HIPS has revolutionized food packaging applications. Picture your local supermarket's dairy section – those yogurt containers and clear disposable cups likely showcase our HIPS grades at work. The material's excellent formability allows for intricate designs, while its impact resistance ensures product protection throughout the supply chain. The natural clarity of the polymer, combined with its ability to accept colors brilliantly, creates packaging that not only protects but also attracts consumers.

The appliance sector harnesses HIPS's unique properties in creating internal components and aesthetic parts. From refrigerator liners to air conditioner components, HIPS provides an excellent balance of properties. Its ease of processing allows manufacturers to create complex parts efficiently, while its impact resistance ensures durability in everyday use. The material's cost-effectiveness makes it particularly attractive for large appliance components where both performance and economics play crucial roles.

In the toy industry, HIPS creates safe, durable products that withstand the rigors of child's play. The material's excellent impact resistance prevents shattering, while its easy processing allows for detailed, colorful designs that capture children's imagination. From building blocks to outdoor toys, HIPS continues to be a preferred choice for toy manufacturers worldwide.
