RUIFENGPOLY™ LP-23 is a general purpose processing aid based on medium-high molecular weight. It is a acrylic copolymer that improves the processability and the performances of rigid PVC formulations. LP-23 is also extremely cost-effective, requiring only very low addition levels for high-quality results.

Chlorinated Polyethylene (CPE135A) from SHANDONG RUIFENG CHEMICAL CO., LTD. is a white, fine powder elastomeric material derived from chlorinated HDPE. It offers excellent flame resistance, weatherability, and flexibility at low temperatures, making it ideal as a PVC impact modifier. This product enhances toughness and impact strength in PVC profiles, pipes, and sheets, and is stable, non-toxic, and easy to blend with other plastics and rubbers.

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.

LUSHAN™ L-74 from Shandong Ruifeng Chemical Co., Ltd is a high molecular, multi-functional fatty acid ester-based PVC external lubricant. It appears as a white or slightly yellow free-flowing powder or debris, odorless, with a melting point of 48-56°C and excellent thermal stability. It enhances PVC processing by improving flowability, surface gloss, and release properties, making it ideal for rigid and soft PVC products such as sheets, profiles, and films.
