As the abbreviation of acrylate copolymer (Acrylic Impact Modifier), impact-resistant ACR, with its unique "core-shell" structure, has become the core material for impact modification of PVC products. Against the backdrop of global PVC production capacity exceeding 60 million tons by 2025, this white powder-like polymer material is driving quality upgrades in industries such as building materials and packaging.
The triple manifestation of performance advantages
1. Mechanical enhancement: By inducing silver streaks and shear bands, the notched impact strength of PVC is increased by 5 to 8 times. Test data from a certain profile enterprise shows that the PVC window frame with 8%ACR added has seen its integrity rate increase to 92% in the -10℃ low-temperature drop hammer test.
2. Processing optimization: The melt viscosity adjustment function increases the extrusion speed by 15%. Due to the adoption of the ACR modified formula, the daily production capacity of a certain pipe production line has increased by 3.2 tons.
3. Weather resistance upgrade: The ester group structure in the molecular chain can effectively block ultraviolet rays. After 2000 hours of xenon lamp aging test, the color difference ΔE of ACR modified products is less than 2.5.
Innovative application scenarios
In the field of new energy vehicles, ACR-modified PVC has been successfully applied to the flame-retardant shells of batteries. Among medical-grade transparent sheet materials, the ACR-K80 model achieves a perfect balance between impact strength and light transmittance.
The Impact resistant ACR produced by AXA Technology Company has higher impact resistance, weather resistance and stability compared with other manufacturers. The company is equipped with a professional technical service team to provide customers with continuous solutions.
