Product Overview
Lihuayi Weiyuan WY-A185 is a high-performance engineering alloy designed to bridge the gap between standard PC/ABS blends and high-cost specialty resins. Its standout feature is a high Heat Deflection Temperature (HDT) of 110°C, which, combined with exceptional melt flow, makes it uniquely suited for thin-wall components that must withstand significant thermal stress.
Whether utilized in automotive dashboards or protective helmet shells, WY-A185 provides the mechanical "backbone" required for structural reliability while ensuring the surface aesthetics demanded by consumer-facing products.
Core Advantages
Elevated Thermal Stability: Maintains structural integrity in environments reaching up to 110 °C, preventing "heat sag" in large automotive or industrial panels.
High-Output Flowability: A melt index of 23 g/10min allows for the effortless filling of complex molds and thin-wall designs, reducing molded-in stress.
Balanced Mechanical Strength: Delivers a high flexural modulus (2300 MPa) for rigidity alongside a tensile strength of 55 MPa.
Safety-Critical Durability: Excellent notched impact resistance (60 kg·cm/cm) ensures energy absorption for helmets and protective gear.
Production Efficiency: A stable processing window leads to consistent mass production with minimal scrap and high dimensional accuracy.

Why Choose WY-A185?
The Thermal Specialist for High-Speed Molding
WY-A185 is engineered for manufacturers who cannot compromise on heat resistance but require the high-flow characteristics needed for fast cycle times. Its unique ability to resist deformation at 110 °C while remaining fluid enough for thin-wall injection molding makes it one of the most versatile "high-heat" grades in the PC/ABS market today.
