RUIFENGPOLY™ LS-50 is a white free-flowing acrylic impact modifier powder designed to enhance the impact resistance of rigid PVC formulations. It offers excellent weatherability, good processability, and long-term durability, making it ideal for outdoor PVC products like window profiles, vinyl siding, fencing, decks, and weatherable injection molded parts. Its low melt viscosity supports high output during processing while maintaining surface quality and color retention.

MBS IMPACT MODIFIER LB-136 from Shandong Ruifeng Chemical Co., Ltd. is a white amorphous powder terpolymer composed of methyl methacrylate, butadiene, and styrene. It enhances rigid PVC by providing high impact resistance, excellent transparency, and improved processability. The modifier reduces gelation time and crease-whitening, making it ideal for PVC blow-molded products, injection molded parts, sheets, films, tubing, and pipe fittings. Its free-flowing, dust-free nature allows for efficient mixing and fast fusion, supporting higher production output and cost savings through reduced dosage.
