TPE, or thermoplastic elastomer, is a type of polymer material that combines the high elasticity, high strength, high resilience, and injection molding properties of rubber. It is widely used in various fields such as automotive, electronics, medical, sports equipment,and household products. In TPE production, wax emulsions can improve yield and product performance, mainly in the following aspects:
Improving processing performance-Lubricating effect: During the TPE pelletizing process, wax emulsions can form a lubricating film between the metal surface of the processing equipment and the TPE melt, reducing the friction between the melt and the equipment. This allows for smoother material flow in the screw, barrel, and other parts, reducing equipment wear and energy consumption.
Demolding effect: It can effectively reduce the adhesion between TPE pellets and the mold surface, making it easier for the pellets to be released from the mold, thus improving production efficiency. It also helps to maintain the integrity and appearance quality of the pellets.
Enhancing-Increasing flexibility: The wax molecules in the wax emulsion can penetrate between the TPE molecular chains, acting as a plasticizer to increase the mobility of the molecular chains.
This thereby improves the flexibility and elasticity of the TPE products, making them feel softer and more comfortable to the touch.
A uniform wax protective film is formed on the surface of TPE products, which can prevent the penetration of moisture,enhancing the water resistance of TPE products and allowing them to maintain good performance in humid environments.
It helps to form a protective film on the surface of TPE, which can to some extent block the erosion of chemical substances.This improves the tolerance of TPE products to chemicals such as acids, bases, and salts, broadening their application scope.
The wax emulsion forms a smooth wax film on the surface of TPE pellets, which can reflect more light, thereby increasing the gloss of the pellets and making the product appearance more lustrous, enhancing market competitiveness.
It can form a separating layer on the surface of TPE pellets, preventing them from sticking to each other, maintaining good dispersibility of the pellets,and facilitating packaging, storage, and subsequent processing.
Wax emulsions are very important in making TPE granules. They help in many ways:
Lubrication: Wax emulsions make a slippery layer between the metal parts of the machine and the hot TPE. This layer reduces friction,so the TPE flows better through the machine.It also helps to save energy and reduces wear and tear on the equipment.
Easier Release from Molds: The wax emulsion makes it easier to remove TPE granules from molds.This speeds up production and keeps the granules looking good.
Softer and More Flexible: The wax in the emulsion makes the TPE chains move more freely.This makes the final product softer and more flexible,which feels nice to touch.
More Waterproof: A thin wax layer on the TPE surface stops water from getting in. This is good for keeping the product's quality in wet conditions.
More Chemical Resistant: The wax layer also protects the TPE from harsh chemicals like acids and salts. This means the product can be used in more places.
Shinier Look: The wax makes the TPE granules shiny. This makes the product more appealing and competitive.
No Sticky Surfaces: The wax layer prevents the granules from sticking together. This makes them easier to handle,pack,and use later.
