Engineering plastics have excellent comprehensive properties, such as high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation. They can be used for a long time in harsh chemical and physical environments and can even replace metals as engineering structural materials.
Advantages of Engineering Plastics
Among many performance advantages, transparency has become the advantage of engineering plastics to "break new ground and overtake on the curve", and it shines in some niche applications. PMMA and PC, as well-known transparent engineering plastics, not only have good optical properties, but also have the advantages of plastic properties such as light weight, impact resistance and easy processing and molding. Therefore, they can replace inorganic glass and are widely used in the optical field and other fields (electrical and electronic, automotive, consumer products, etc.).
Injection molding challenges
However, as engineering plastics are used in more and more occasions, the performance requirements for the materials themselves are becoming higher and higher. In addition to the traditional requirements of high strength, high and low temperature impact resistance, anti-static, antibacterial, corrosion resistance, and high heat resistance, processing continuity without affecting transparency has also become a major problem that plagues injection molding production, especially for the continuous injection molding of products with multiple cavities in one mold and complex structures. Unsmooth demoulding leads to long processing cycles, easy scratches or even breakage on the surface of the parts, and blockage of the flow channel.
Montan wax
Montan wax is often used as a continuous demoulding solution because of its excellent temperature resistance and ability to match polyester processing temperatures without failure/precipitation. The presence of polar and non-polar segments can provide both internal and external lubrication and compatibility. However, since montan wax is a mineral non-renewable resource (derived from lignite), the resulting supply problems have forced customers to seek new alternatives.
Honeywell HPL-6901 ester wax
Honeywell HPL-6901 ester wax has excellent lubrication and temperature resistance, good compatibility with polyester, and tends to be externally lubricated. It is especially suitable for the modification of transparent products such as PC and PMMA. The addition amount is 0.3-0.5%. It helps to improve the demoulding performance while having little effect on the transparency of the product. It can help customers improve the processing efficiency of products and the appearance of terminal products. Compared with the classic PETS (pentaerythritol stearate), it has a higher melting point and back-end demoulding properties. For non-transparent fields, HPL-6901 can also be used as processing lubrication and demoulding, such as PC+GF, PC/ABS, PET+GF and other formulation systems.
