TPE granules stick together when granulating? Three solutions Processing Technology: Adjust screw speed and barrel temperature for even mixing and full cooling, use low shear molding and nitrogen purification to reduce temperature, and ensure granules cool below 30°C before packaging. In hot weather, add ice to the cooling water to lower temperature. Formula: Incorporate an appropriate amount of external lubricant to prevent overuse. Raw Materials: Utilize high molecular weight SEBS with a star-shaped structure, ensuring it does not absorb more than 2.5 times its weight in oil and add fillers afterward.

Polyvinyl chloride (PVC) is a polymer formed by the polymerization of vinyl chloride monomer (VCM) in the presence of initiators such as peroxides and azo compounds or under the action of light or heat according to the free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

TPV sealing strips have better elasticity and aging resistance than TPE. Why are they gradually being replaced by TPE in daily life applications? The main reasons are as follows:1. Environmental protection 2. Material performance 3. Processing cost

PS material has high rigidity and hardness, but it is brittle and easy to crack and break under impact. By adding toughening agent, the impact strength of PS can be effectively improved, so that it can better withstand external impact, thereby improving the service life and safety of the product.

If you make TPE pellets, you will definitely encounter customers who ask for transparent TPE materials to make some transparent toys or transparent parts. However, they often encounter such a problem: they use transparent TPE materials to produce test molds, but the transparency of the TPE products produced is not satisfactory. What is the reason for this?

TPE and TPU are both formed by extrusion. TPE has better feel and flexibility than TPU and is cheaper than TPU. In terms of hardness, TPE can reach 0A-100A, while TPU can only reach a minimum of 55A. Although they are both thermoplastic elastomer plastics, TPU has a higher bending modulus than TPE.

Filler masterbatch refers to the granules and powders obtained by mixing and kneading various additives and fillers with a small amount of carrier resin in the process of plastic processing and molding for the convenience of operation. The main component of filler masterbatch is filler, which is mainly used for the processing and molding of polyolefins (polyethylene and polypropylene), and is also called polyolefin filler masterbatch.
