Market trends: Lightweight, high complexity, and aesthetic integration
From new energy vehicles to wearable smart terminals, product structures are becoming increasingly complex and appearance requirements are getting stricter. The industry has put forward three new demands for plastic raw materials:
✔ Lightweight, cost reduction and carbon emission reduction
✔ Thin-walled complex structure design
✔ High surface quality and functional integration
Traditional ABS and PC monomer resins are difficult to balance all aspects, and ABS Polycarbonate Plastic PC-345 is precisely the preferred composite material to address this trend.
01 | Material highlights: Performance advantages of PC-345
🔹 high fluidity, breaking through design limitations
Optimize the flow formula, enhance the mold filling effect, and be suitable for ultra-thin, microstructure, and complex geometry products.
🔹 low shrinkage, ensuring dimensional stability
Effectively reduce the risk of deformation and stress cracking, and meet the requirements of high-precision assembly.
🔹 Good processability, improving production efficiency
It comes with a self-lubricating demolding agent, which shortens the injection molding cycle, extends the service life of the mold, and reduces the overall cost.
🔹 has excellent comprehensive mechanical properties
Combining the toughness of ABS with the rigidity of PC, it ensures that the products have excellent impact resistance and durability, and are suitable for a wide range of demanding applications.
