Key features

Ultra-high thermal stability effectively suppresses PVC degradation during processing, minimizing yellowing and ensuring consistent product quality across extrusion, injection, calendering and blow mo
Excellent initial-color retention and high transparency deliver crystal-clear appearance for rigid PVC sheets, transparent pipes and food packaging films.
Perfect compatibility with PVC resin ensures uniform dispersion, widens processing temperature window, reduces equipment wear and improves overall production smoothness.
Lead-free non-toxic formulation fully replaces traditional lead-based stabilizers, meeting strict safety standards for food contact and medical device applications.
Low dosage with high efficiency reduces overall stabilizer consumption under equal processing conditions, helping customers cut down formulation cost comprehensively.
Fully compliant with EU REACH, RoHS and FDA food contact regulations, making it ideal for export-oriented PVC manufacturers
Professional technical team provides on-site process guidance to help customers quickly optimize formulation and maximize production efficiency.

AI-Powered supplier vetting

SummaryThe supplier is identified as a trading company in Shengzhou, Shaoxing, with a business scope covering chemical raw materials, plastic auxiliaries, plastic raw materials, chemical equipment, technical consulting, and import/export activities. It reports 15 years of exporting experience and approximately 90% export sales, but no overseas warehouses, showrooms, agents, branches, or in-stock service capacity. Service and complaint-handling procedures exist but lack written records, while supplier approval documentation lacks signatures or dates. Innovation evidence is mixed: the supplier provides ODM and OEM services and has one R&D engineer, but reported no new products in the past year and has no available SDK. Customization from samples is available. Production capability is not demonstrated because the company is classified as a trading company and no manufacturing capacity is provided. Customer cases are not sufficiently documented; OEM service for well-known brands is stated, but no specific customers...
Supplier typeThe supplier is explicitly classified as a trading company, with its business scope focused on sales of chemical and plastic-related products, technical consulting, and import/export activities. This indicates a commercial intermediary or distributor profile rather than a clearly documented manufacturer.
After-Sales capabilityThe supplier has procedures for service capability, corrective and preventive actions, and customer complaints, but no written records. It also reports no in-stock service capacity, overseas warehouse, showroom, agent, branch, or overseas service coverage, while stated peak- and off-season lead times are both one month. The documented after-sales infrastructure is therefore limited.
Production capacityThe company is explicitly identified as a trading company, and its stated scope centers on product sales, consulting, and import/export rather than manufacturing. No factory, production line, manufacturing capacity, or production equipment is provided; the quality-control equipment quantity is stated as zero. Production capability is not demonstrated.
Customization capabilityThe supplier states that it provides customization from samples and offers ODM services. These are explicit indications of product customization and design-manufacturing support, although no scope, technical process, or completed customization examples are provided.

Product Q&A

Q:What is the core quality specification of your methyltin mercaptide stabilizer?
A:
Our product strictly controls the total tin content above 19.0% and methyltin content above 18.0%, with free tin ion content limited below 0.1%. Each batch undergoes 3 independent tests before delivery to ensure consistent thermal stability, transparency and low volatility, completely avoiding color drift during PVC processing.
Q:Can your product maintain stable performance after long-term storage?
A:
Yes. Our methyltin mercaptide is sealed in 200L galvanized drums with nitrogen protection. Under 0-30 degree dry storage conditions, its shelf life reaches 24 months. Even after 12 months of storage, the thermal stability retention rate is still above 98%, far exceeding the industry average level.
Q:What types of PVC products is this stabilizer suitable for?
A:
It is widely applicable to almost all rigid PVC products, including transparent food packaging containers, medical PVC tubes, PVC pipes and profiles, calendered PVC sheets, blow-molded bottles and injection-molded hard packaging. It also works perfectly for suspension, emulsion and bulk PVC homopolymers and copolymers.
Q:What is the recommended dosage in PVC formulation?
A:
For general rigid PVC products, the recommended dosage is 1.0-2.5 PHR (parts per hundred resin). For high-transparency food contact products, the dosage can be adjusted to 1.5-2.0 PHR. We will provide targeted dosage suggestions according to your specific processing technology and final product requirements.
Q:Can it replace traditional lead-based stabilizers directly without changing existing production lines?
A:
Yes. Our methyltin mercaptide can be directly substituted into your original formulation without major modification to existing extrusion, calendering or injection molding equipment. It even helps widen the processing temperature window and reduce equipment energy consumption by 5-8%.
