Products Description
HIPS Granules, also known as High Impact Polystyrene, is a revolutionary thermoplastic material made of modified polystyrene with an elastomer. With its milky-white opaque appearance, high impact strength (5-10 times higher than GPPS), and excellent flexibility, HIPS Granules are perfect for use in various applications. Its ability to be molded in any color provides the perfect solution for products that require aesthetic appeal. At the same time, its excellent chemical resistance, electrical properties, and processing characteristics make it suitable for a wide range of product applications.
HIPS granules Features
Advantages
- Excellent flowability: HIPS has good flowability, which makes it able to fill the mold quickly during the injection molding process.
- High Impact Strength: HIPS has very strong impact resistance, which can effectively resist external impacts and protect the product from being easily broken.
- Easy coloring: HIPS is easy to color and can be customized in various colors according to demand.
- Excellent electrical insulation: HIPS has good electrical insulation, suitable for occasions requiring electrical insulation.
- Higher surface hardness: HIPS has a higher surface hardness that provides better abrasion and scratch resistance.
Disadvantages
- Rubber material content affects fluidity: HIPS plastic has 15% rubber material content, which affects its fluidity to some extent.
- Slow cooling: HIPS plastic cools slowly, requiring longer holding pressure times and speeds, and molds also need to have excellent heat exchange to reduce shrinkage and shape changes.
