Flame Retardant Synergist For Elastomers
Qingdao Topsen chemical supplies Topfine® N98, an amorphous silicon dioxide synergist designed to enhance the efficiency of flame-retardant additives in elastomers and thermoplastics. The product consists of spherical primary particles with a mean diameter of 150 nm, offering high surface area and uniform dispersion. It is non-toxic, inert, and does not decompose under fire conditions, making it suitable for high-performance compound formulations.
Topfine® N98 functions as a rheology modifier and char-strengthening agent, allowing up to 30% reduction in the use of traditional flame retardants like ATH or APP without compromising fire performance. Its ball-bearing effect reduces mixing torque, lowers extruder plate-out, and improves filler dispersion. The material is compatible with TPE, ABS, and dark rubber systems and does not interfere with colorants or curing systems.
Buyers include compounders in the automotive, wire & cable, and industrial elastomer sectors seeking to reduce additive loadings while maintaining flame resistance and fatigue performance. The product is packaged in 25 kg bags, with custom packaging available. Lead time is 15 - 20 days from order confirmation. Buyers must confirm compatibility with their base polymer and test dispersion quality before scaling production.

Sourcing Flame Retardant Synergist For Elastomers from Qingdao Topsen chemical - China Import Guide
Verify the particle size distribution and moisture content of each batch before acceptance. Request a certificate of analysis showing specific surface area and ash content. Confirm compatibility with your base polymer and curing system through small-scale trials. Do not assume performance from supplier claims without independent testing under your processing conditions.
Lead time is stated as 15 - 20 days but may vary by order volume. Incoterms are not specified - confirm whether FOB Qingdao, CIF, or EXW applies. Payment terms are not listed; buyers must negotiate T/T, L/C, or advance payment directly. Packaging is 25 kg polypropylene bags, but custom labeling or bulk containers may be available. Confirm export documentation requirements for your country’s chemical import regulations.
Conduct incoming inspection for flowability, color consistency, and absence of lumps. Test dispersion in a small batch using torque rheometry or microscopy. Retain samples for batch traceability. Ensure the product is stored in a dry environment prior to use. Request a safety data sheet (SDS) and confirm compliance with local chemical handling regulations, especially if used in food-contact or medical applications.
