KM-355P is an ACR impact modifier tailored for outdoor rigid PVC products. It boosts PVC articles' impact strength and weather resistance, aids plasticization to raise extrusion output, cuts down acrylic processing aid usage, and improves post-extrusion shrinkage—making it perfect for diverse outdoor PVC uses.
Excellent impact strength enhances the durability of rigid PVC products.
Superior weather resistance fits well with outdoor environments.
Effectively promotes plasticization, increasing extrusion output.
Helps reduce post-extrusion shrinkage for stable product dimensions.
Used in outdoor rigid PVC products like window frames, wall panels, building siding, and fences.
Applied in PVC pipes, fittings, and various injection-molded PVC components.
