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.

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.

Whether the venting screw leaks material is directly related to the extrusion process, plastic properties, and the design of the screw and vent. Therefore, when manufacturers use venting extruders for production and processing, they must have a detailed understanding of the processing technology, resin characteristics, and equipment performance to ensure that the venting extruder can operate normally and stably.

Advances in twin screw extruders offer opportunities for processing that is shear sensitive or limited by torque and/or temperature. Regardless of the formulation and/or end product, it is important for processors to understand and employ the latest technology to achieve success.

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.
