ACR for pvc profile

1. excellent impact strength under low-temperature conditions 2. excellent long-term weather-resistance.

  HL-52 is an acrylic impact modifier developed by our R&D center. It is used to improve the impact-strength of PVC products with glossy surface. It is recommended for applications such as PVC profile and PVC pipe etc. where good outdoor weathering and low-temperature impact resistance are critical properties.
