LG Chem ABS XR404: Heat-Resistant ABS Plastics for Automotive
Product Struction
What are ABS Plastics
Among engineering plastic systems, ABS (acrylonitrile-butadiene-styrene copolymer) is one of the most widely used ABS plastics, renowned for its excellent processing performance and mechanical strength. LG Chem's ABS XR404 has undergone heat resistance improvement on the basis of traditional ABS, making it a material that combines rigidity, toughness and thermal stability, thus becoming an ideal material for both functionality and appearance in the automotive and electronics manufacturing industries.
This material is specially designed for Injection Molding. It can maintain stable flow and filling performance in complex molds and precision structural parts, reduce part shrinkage and deformation problems, and provide manufacturers with a more reliable abs plastics solution.

1. Performance Analysis: The Balance between Thermal Stability and Mechanical Strength
LG Chem ABS XR404 achieves performance balance in terms of heat, force and electricity by optimizing the polymerization ratio and adding heat stabilizers.
・Better thermal stability: The material can maintain mechanical integrity even when exposed to heat for a long time, making it suitable for medium-temperature working areas such as air conditioning outlets and instrument panels in automobiles.
・Mechanical toughness stability: It has a good energy absorption capacity under impact and bending loads, preventing assembly risks caused by brittle cracking of structural components.
・Electrical insulation characteristics: High volume resistivity and dielectric strength ensure safety and reliability when used as electronic device enclosures.
Because of this, XR404 can simultaneously meet multiple standards of automotive and electronic manufacturers in terms of heat resistance, structural strength and surface quality, and is a typical representative of highly practical abs plastics.

4. Process Compatibility: High stability performance of injection molding
ABS XR404 is in granular raw material form and is suitable for mainstream injection molding equipment. Its moderate melt flow index (MFR) provides excellent fluidity and molding efficiency, and it also performs well in the production of complex structural parts and thin-walled products.
During the injection molding process, XR404 is not sensitive to mold temperature and cooling rate, which helps to shorten the production cycle and improve the yield rate. This feature is particularly crucial for mass-produced automotive parts or electronic housings.
5. Industry Trends: The continuous growth in demand for heat-resistant ABS
With the popularization of automotive lightweighting, electrification and smart electronic devices, the demand for abs plastics that combines structural performance and appearance texture is increasing day by day. The launch of LG Chem XR404 is in line with this trend. Its formula strikes a balance between thermal stability and mechanical toughness, enabling it to perform stably in a wider temperature range and more complex application environments.
In the future market, ABS materials with heat resistance and good injection molding performance will continue to be important basic materials for the integrated design of automotive electronics and the appearance optimization of home appliances.
