As industrial safety standards keep rising globally, fabric-supported nitrile gloves have become essential PPE for construction, auto maintenance, logistics and metalworking sectors. Glove manufacturers constantly search for latex raw materials that balance easy processing, low production waste and superior finished glove performance. Zhejiang Ruico Advanced Materials has developed RFA-7631 medium acrylonitrile carboxylated NBR latex specially for coated fabric glove production, solving many common processing pain points of traditional nitrile latex and bringing tangible economic benefits to glove factories.

RFA-7631 is a milky white aqueous colloidal butadiene-acrylonitrile copolymer dispersion equipped with matched emulsifiers and built-in antioxidants, with stable and controllable core physical indexes. Its solid content is controlled at 45.0±1 wt%, a suitable concentration that ensures uniform coating without overly thick or thin films. The pH range of 8.0–9.0 is highly compatible with most vulcanizing agents, pigments and foaming additives, removing the extra step of pH adjustment during compounding. Measured at 25°C with Brookfield LV viscometer, its viscosity is below 100 cps, guaranteeing smooth flow in dipping tanks and uniform mixing with all chemical auxiliaries. With medium acrylonitrile content, it avoids the drawbacks of high-AN rigid coatings and low-AN poor abrasion resistance, achieving a perfect balance of wear resistance and soft touch. All listed parameters are typical reference values; manufacturers can obtain official sales specifications from Ruico for formal mass production standards.

The processing advantages of RFA-7631 stand out most on dipping production lines. First of all, it has excellent colloidal stability, requiring no strict feeding sequences during compounding. Workers can add various additives conveniently without worrying about latex coagulation, and mixed latex can maintain stability for a long time to reduce waste from invalid batches. Secondly, its fast gelling feature effectively cuts raw material loss. Ordinary nitrile latex drips severely after fabric liners are lifted out of the liquid tank, wasting latex and creating slippery workshop floors. RFA-7631 quickly forms a solid coating layer on fabric upon contact with air, drastically reducing dripping loss and stabilizing liquid levels in dipping tanks to improve overall yield. Thirdly, it delivers remarkable foaming performance. Only a small dosage of foaming agent is needed to form delicate, non-collapsible foam layers, lowering auxiliary material costs while making gloves lighter and more breathable for long-hour work. In addition, the latex adapts to different production equipment and all kinds of fabric liners, requiring minimal formula modification when factories switch raw material suppliers. Simple full stirring before use can secure consistent coating quality.

Finished gloves made with RFA-7631 fully satisfy end users’ dual demands of durability and flexibility. Carboxyl groups in the copolymer structure strengthen crosslinking after vulcanization, greatly boosting the coating’s abrasion resistance to withstand frequent friction with metal, concrete and sharp objects, extending glove service life. Meanwhile, the optimized polymer structure retains great elasticity, so gloves stay soft without limiting finger movement, maintaining sensitive tactile control for tool operation and precision assembly. As pure synthetic nitrile latex without natural rubber protein, it eliminates the risk of allergic reactions, complying with strict workplace health regulations. It also shows good resistance to mechanical oil and mild industrial detergents, far outperforming natural rubber gloves in oil-contacted working environments.

Ruico sets complete packaging, storage and safety operation rules to protect product quality. RFA-7631 is packed in Flexitanks and IBC tanks. Unopened original packaging contains anti-microbial ingredients to prevent mildew and bacterial reproduction during transportation and storage, with a 6-month shelf life when stored in cool, dark warehouses. Freezing is strictly forbidden, as low temperature will irreversibly destroy the latex dispersion system. Once packaging is opened, factories must keep mixing equipment clean and add biocides appropriately to avoid microbial contamination. All operating staff must follow safety instructions in the latest SDS provided by Ruico: prevent direct eye and long-time skin contact, and complete large-batch mixing work in well-ventilated spaces. Spilled latex makes floors slippery, so anti-slip mats and cleaning supplies must be prepared in production zones.

Ruico provides full technical support to every partner. Since finished glove quality is affected by each factory’s unique production process, fabric substrate and curing parameters, Ruico requires customers to carry out multiple small trial tests matching local certification standards before mass production. Professional technical staff can answer formulation and coating failure questions at any time. Customers can contact Ruico via phone, fax, email or official website to request SDS, formulation guides or arrange factory visits at its Huzhou headquarters address.

For glove manufacturers eager to optimize production efficiency and upgrade product quality, RFA-7631 is a cost-effective, all-round reliable carboxylated NBR latex. It simplifies compounding processes, reduces raw material waste and produces comfortable, long-service-life industrial supported gloves. Supported by standardized chemical storage safety protocols and thoughtful one-stop technical service from Zhejiang Ruico Advanced Materials, RFA-7631 has become a preferred latex material for modern PPE manufacturers aiming for high yield and competitive finished gloves.
