About Shandong Shituo High Molecular Weight Material Co., Ltd. - Polyvinyl Chloride (PVC) Supplier in China

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.

Product Range and Specialties of Shandong Shituo High Molecular Weight Material Co., Ltd.

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.

Trade and Export Information - Shandong Shituo High Molecular Weight Material Co., Ltd.

China remains one of the world’s largest exporters of PVC additives, with shipments directed to Europe, North America, and Southeast Asian markets. HS code 3916 covers PVC compounds and mixtures, while related masterbatch products may fall under HS code 3915. International buyers usually require ISO 9001 quality management certification, ISO 14001 environmental compliance, and REACH registration for chemical safety within the EU. RoHS compliance is also common for additives destined for electronic or consumer‑goods applications. Export logistics often involve 20‑ft or 40‑ft containers, bulk drums (200 L), or jumbo bags (25 kg), and Incoterms such as FOB Shanghai or CIF destination ports are standard practice. Chinese customs inspections routinely verify SDS documentation and conformity with the Harmonised System description before clearance.

Sourcing from Shandong Shituo High Molecular Weight Material Co., Ltd. - Buyer Guidance

When sourcing these PVC and acrylic additives, request a technical data sheet that details melt flow index, impact strength, and recommended usage levels. A safety data sheet (SDS) and REACH registration number should be obtained to confirm regulatory compliance for EU or US markets. Buyers typically ask for a sample batch of 5 - 10 kg to verify compatibility with their resin system before confirming a standard minimum order of 5 metric tons. Lead times for bulk production in China are commonly 30 - 45 days after order confirmation, assuming all test reports and certifications are provided.

What types of PVC additives are listed in the supplier’s catalogue?

The catalogue includes a PVC processing aid (YM series), a PVC impact modifier (YM‑355), and a PVC lubricant modifier (YM‑175), each formulated for use in PVC compound formulations.

What acrylic processing aids does the supplier offer?

Two acrylic‑based aids are listed: PA‑828 and K‑125, both intended to improve flow and surface properties in PVC or acrylic resin systems.

Which HS codes are typically applied to these products?

PVC additives and masterbatches are generally classified under HS code 3916, while pure acrylic processing aids may also fall under the same chapter for polymer compounds.

What certifications should a buyer verify for PVC additives from China?

Buyers should request ISO 9001 quality management certification, REACH registration for the EU, and RoHS compliance if the end use involves electronic equipment.

What packaging formats are common for bulk shipments of these additives?

Bulk shipments are usually packed in 20‑ft or 40‑ft containers, with inner packaging in 200 L steel drums or 25 kg jumbo bags, sealed to prevent moisture ingress.

What is a typical minimum order quantity and lead time for the acrylic processing aid PA‑828?

The typical MOQ is 5 metric tons, and lead time after order confirmation ranges from 30 to 45 days, depending on production scheduling.

How can a buyer obtain sample material for testing?

Buyers can request a sample of 5 - 10 kg, which the supplier can provide after receipt of a signed sample agreement and confirmation of intended testing parameters.

Are the listed products likely to meet REACH or RoHS requirements?

While the supplier’s specific certifications are not listed, REACH registration and RoHS compliance are standard requirements for PVC additives destined for EU markets and should be confirmed with the supplier before purchase.
