AI-Powered supplier vetting

SummaryQingdao New Sanda Industry Co., Ltd. is identified as both a trading company and manufacturer/factory in China, focused on chemicals and construction-related products. The supplier reports ISO-series management certifications, two production lines, 21–30 quality-control staff, and peak- and off-peak order fulfillment within 15 working days. Its stated capabilities include R&D, customized formulations, formulation optimization, application testing, troubleshooting, multilingual documentation, and after-sales support. The supplier reports extensive export coverage and began exporting in 2015, but the available trade evidence shows only one recorded transaction and one associated buyer. Financial credibility cannot be assessed because financial data is excluded from evaluation.

Supplier typeThe supplier is explicitly classified as both a Trading Company and Manufacturer/Factory. Its stated business focuses on chemical products and industrial additives, including Titanium Dioxide, HPMC, VAE, HEC, CMC, and related materials.

CertificationsThe supplier lists ISO 9000, ISO 14001, ISO 9001, ISO 14000, and ISO 20000 certifications. These stated certifications provide explicit evidence of certified management-system coverage, although the slices do not provide certificate numbers, validity dates, or scope details.

After-Sales capabilityThe supplier states that it provides after-sales service, multilingual documentation, formulation optimization, application testing, and troubleshooting. These are explicit service offerings supporting customers after product delivery.

R&D capabilityThe supplier describes a dedicated R&D team, technical innovation, market-responsive product development, and feedback integration from global partners. It also reports total R&D engineer experience of 11–20 years, supporting an established innovation function.

Production capacityThe supplier presents itself as a chemical manufacturer and reports two production lines, 21–30 quality-control staff, and fulfillment within 15 working days in both peak and off-peak periods. Its product portfolio and end-to-end commercial supply description support production capability, although total output details are not evaluated here.

Customization capabilityThe supplier explicitly offers customized formulations for specific application challenges and provides formulation optimization, application testing, and troubleshooting. Its process includes sample testing through full-scale commercial supply, indicating support for tailored industrial additive solutions.

Product Q&A

Q:What is the main use of CPE 135A?

CPE 135A is a chlorinated polyethylene used primarily as an impact modifier for PVC. It significantly improves low-temperature toughness and impact strength of PVC products. Widely used in profiles, pipes, sheets, cable sheathing, and more.

Q:How does Chlorinated Polyethylene content affect performance?

Chlorinated Polyethylene content determines polarity and compatibility with PVC. The typical 35% Chlorinated Polyethylene content in CPE 135A offers optimal compatibility with PVC and the best toughening efficiency. Lower content reduces compatibility; higher content reduces toughening efficiency.

Q:What is the recommended addition level of CPE 135A?

For PVC profiles and pipes, typical addition is 5-8 phr (parts per hundred resin). For high-performance impact modification, 10-15 phr can be used. Optimal dosage should be determined through testing.

Q:How should CPE 135A be stored? What is its shelf life?

Store in a cool, dry, well-ventilated area, away from moisture and direct sunlight. Shelf life is 12 months from production date. Reseal after opening to prevent moisture absorption and caking.

Q:What is the difference between CPE 135A and CPE 135B?

Both have similar Chlorinated Polyethylene content (approx. 35%), but differ in Mooney viscosity. CPE 135A has higher viscosity (ML 60-80), suitable for rigid PVC toughening. CPE 135B has lower viscosity (ML 40-60), offering better flowability for flexible PVC or highly filled systems.
