Shandong Shituo High Molecular Weight Material Co., Ltd.

China, specifically Shandong province, hosts five active product listings from Shandong Shituo High Molecular Weight Material Co., Ltd. The catalogue includes PVC processing aid YM series, acrylic processing aid PA-828, PVC impact modifier YM-355, PVC lubricant modifier YM-175, and K‑125 acrylic processing aid. These items fall under the broader categories of Polyvinyl Chloride (PVC) additives and masterbatch compounds, reflecting the supplier’s focus on polymer processing enhancers. The product titles indicate a mix of processing aids, impact modifiers, and lubricant modifiers that are typical inputs for PVC resin formulation.

The listed products are generally classified under HS chapter 39, with PVC additives commonly using HS code 3916 for compounds and mixtures. Such additives are used in extrusion, injection molding, and profile extrusion to improve flow, impact resistance, and processing stability. The catalogue’s emphasis on both PVC‑specific and acrylic‑based aids suggests compatibility with a range of PVC grades, from rigid to flexible formulations. Buyers can expect these materials to be supplied in bulk packaging suitable for large‑scale manufacturing.

The five catalogue items consist of two acrylic‑based processing aids (PA‑828 and K‑125) and three PVC‑focused additives (YM series processing aid, YM‑355 impact modifier, and YM‑175 lubricant modifier). In the PVC industry, processing aids are typically low‑molecular‑weight compounds added at 0.1 - 0.5 % by weight to lower melt viscosity and improve extrusion stability. Acrylic processing aids often target clarity and surface finish, with usage rates of 0.2 - 0.8 % and melt flow index (MFI) values between 5 and 30 g/10 min. Impact modifiers such as rubber‑based or core‑shell types are specified by Izod impact values, frequently exceeding 30 kJ/m² at - 20 °C. Lubricant modifiers are evaluated by melt torque reduction and may be supplied with a viscosity index of 80 - 120. Typical specifications for these categories include compliance with ISO 1629 for plasticizers and ISO 1133 for melt flow testing.
