Elastomer Granulator Production Process And Flow

Using styrene block copolymers (SBS, SEBS, SEPS, SIS, etc.) as the basic material, supplemented with other polymers, fillers and processing aids Thermoplastic elastomer blends,

As follows:

1. Styrene block copolymer elastomer polymer: single specification or multiple specifications composite, the role is to provide elasticity

2. Filler oil: usually straight-chain alkane oil such as white oil, the role is to adjust hardness and fluidity

3. Other polymers, such as polypropylene or other polyolefins, may also be other engineering plastics or engineering elastomers such as TPU, TPEE, which may be used alone or in combination with multiple materials, the role is to adjust hardness, control costs, and/or give TPE blends specific properties

4. Compatibilizer: used to improve the compatibility between polar materials and non-polar materials, improve material properties, and can also improve the compatibility between TPE and polar engineering plastic substrates in secondary injection molding (encapsulation) and other occasions

5. Other functional modifiers: give TPE other special properties, such as polyphenylene ether (PPO) can improve the styrene chain segment in styrene block copolymers Glass transition temperature, thereby improving the heat resistance of TPE blends, etc.

6. Fillers: usually mineral fillers such as talcum powder and calcium carbonate, the main function is cost control, in addition to the mechanical strength, hardness and other properties of the material also have a certain impact

7. Functional additives: such as flame retardants, lubricants, antistatic agents, antibacterial agents, etc., used to give the blended elastomer specific properties;

8. Antioxidants/anti-ultraviolet aging agents: used to slow down the degradation/aging of materials during thermal processing and use

9. Elastomer granulator process: Add to a certain proportion------high mixer----TPR granulator-------water ring granulator-------centrifugal dehydrator extended air-cooled vibrating screen------finished product silo
