When TPE strands are cut into pellets, the problem of the extruder die head breaking as soon as it is pulled out can be located and solved from the following four aspects:1. Adjust the plasticizing temperature 2. Adjustment of oil filling amount 3. Filler adjustment 4. SEBS content adjustment

Process parameters affecting internal mixer mixing 1. Mixing procedure and order of adding materials 2. Mixing temperature 3. Mixing time 4. Rotor speed

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.

Corrosive, abrasive, and high-temperature resins can inadvertently degrade screws and barrels. Certain engineered materials, thermoplastic elastomers, and newly developed biopolymers often create corrosive conditions that rapidly degrade equipment. Reinforcement materials such as glass fibers, balls, and other fillers and additives are abrasive and can also cause damage to equipment, especially feed screws and barrels.

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?

High temperature melt pump is an indispensable equipment for conveying, pressurizing and metering high temperature and high viscosity polymer melt. Compared with other types of pumps, high temperature melt pump has compact structure, reliable operation, low energy consumption, high volumetric efficiency, small shearing effect on melt, stable flow rate under high viscosity and high pressure, and no outlet pressure fluctuation. The unique advantages of this pump and its key role in the process make it play an irreplaceable role in polyester production.

In the PVC (polyvinyl chloride) processing technology, mixing technology plays a vital role as the first process in the production of PVC products. However, many companies often do not pay enough attention to the mixing process, which leads to misunderstandings among workers about mixing technology, thinking that it is enough to just mix the materials evenly. This article will introduce the role, principle and process of PVC mixing in detail to help readers fully understand PVC mixing technology.
