What material is PET, how to improve the mould release performance of PET products and product quality?

PET (Polyethylene terephthalate) is a thermoplastic polyester with a variety of excellent physical, chemical and mechanical properties, so it has a wide range of applications in industry and daily life.

The main characteristics of PET include:

1.High transparency and gloss, making it an ideal choice for manufacturing transparent packaging materials.

2.Good mechanical properties, including high tensile strength, bending strength and impact strength, and excellent wear resistance.

3.Good heat resistance, can maintain stable physical properties at high temperatures, and its melting point is between 250-260.

4.High chemical stability, good resistance to most organic solvents and acid and alkaline substances.

5.Excellent electrical insulation performance, suitable for electronic field.

6.Environmental protection, recyclable, environmentally friendly.

PET has a wide range of applications, including:

1.Packaging materials: such as beverage bottles, food packaging boxes, etc., occupy an important position in the packaging industry because of its transparency and chemical resistance.

2.Fiber products: PET is also an important raw material of synthetic fibers, such as polyester, used to make clothes, home textiles and so on.

3.Engineering plastics: They are also widely used in industrial fields such as mechanical parts and electronic equipment shells.

4.Film and tape: It is also used in electronic equipment, such as insulation materials, capacitors, cables, etc.

Although PET has many advantages, it also has some disadvantages, such as poor resistance to hydrolysis, which may occur under high temperature and alkaline conditions. In addition, the resistance of PET to some chemicals is weak, the thermal deformation temperature is relatively low, and the processing difficulty is high. In order to increase the processing performance of PET, an appropriate amount of processing additives can be added, thereby improving the processing fluidity, mould release performance and surface quality of PET.

In order to increase the processing fluidity of PET materials, the following methods can be taken:

1.Add nucleating agent and crystallization accelerator: increase the crystallization rate of PET and reduce the mold temperature.

2.Glass fiber reinforced modification: The notch impact strength and thermal deformation temperature of PET are increased by adding glass fiber that has been surface treated.

3.Select the right processing AIDS: High lubrication SILIKE SILIMER 5150 is a functionally modified silicon wax with a special structure, good compatibility with matrix resins, no precipitation and no impact on product appearance and finish. SILIMER 5150 is widely used to improve the scratch resistance of plastics and composite products such as PE, PP, PVC, PET, ABS, thermoplastic elastomers, plastic alloys, wood plastics, etc., to keep the surface of the product bright and textured for a long time, effectively improve the lubricity and release of materials during processing.

Functionally modified silicone additive SILIMER 5150, Effectively improve the mould release performance of PET products without affecting the transparency of products

High-lubrication SILIMER 5150 is a functionally modified silicone additive, which can be used in PE, PP, PVC, PET, ABS, thermoplastic elastomers, plastic alloy, wood-plastic and other plastics and composite products, which can improve the scratch resistance of the products. Keep the surface of the product bright and textured for a long time. It can effectively improve the lubricity and mold release during the material processing, and make the product reduction degree better. At the same time, it has a special structure, good compatibility with the matrix resin, no precipitation, and no influence on the appearance and surface treatment of the product.
