In today’s fiercely competitive PPE industry, fabric-supported nitrile gloves dominate industrial scenarios such as machinery maintenance, construction, logistics and auto repair. However, most conventional nitrile latex brings consistent troubles to glove producers: unstable compounding, severe dripping loss, excessive foaming agent consumption and finished gloves that fail to balance softness and wear resistance. Ruico’s RFA-7631 medium acrylonitrile carboxylated NBR latex is tailor-made for fabric liner dipping production lines, solving these common manufacturing pain points and helping factories improve production efficiency and product competitiveness simultaneously.

RFA-7631 is a milky white aqueous colloidal dispersion of carboxylated butadiene-acrylonitrile copolymer, equipped with proprietary emulsifier system and built-in antioxidant to maintain stable colloidal state. Its core physical and chemical parameters are strictly controlled to guarantee stable mass production results. The solid content is fixed at 45.0 ±1 wt%, a moderate concentration that avoids pinholes from ultra-thin coatings and sediment caused by overly thick latex slurry. The pH value maintains a stable range of 8.0–9.0, which is highly compatible with vulcanizing agents, pigments and foaming additives commonly used in glove workshops, removing the extra cost of pH regulators. Under standard testing environments (Brookfield LV viscometer, spindle 2, 30rpm, 25°C), viscosity is controlled below 100 cps, enabling smooth circulation in dipping tanks and quick uniform mixing with all auxiliary chemicals. Its medium acrylonitrile design creates a perfect balance that many latex grades cannot achieve: high-AN latex has great oil resistance but forms rigid gloves limiting finger movement, while low-AN latex delivers soft touch yet poor abrasion resistance. RFA-7631 perfectly combines the two merits. All listed indicators are typical reference values; manufacturers can contact Ruico to obtain official sales specifications as formal standards for bulk orders.

The outstanding processing performance of RFA-7631 brings direct economic benefits to production workshops. Benefiting from strong self-stabilization, there are no harsh requirements for compounding operations. Technicians can add anti-aging agents, color pastes and biocides freely without complicated segmented feeding, and compounded latex can keep uniform quality for a long time in storage tanks, reducing waste from invalid coagulated batches. Its prominent fast gelling feature greatly cuts raw material waste. After fabric liners are lifted from dipping tanks, ordinary nitrile latex will continuously drip off, wasting expensive latex and forming slippery floors with hidden safety risks. RFA-7631 quickly forms a compact coating layer on fabric once exposed to air, minimizing dripping loss and stabilizing liquid levels in dipping tanks during continuous shifts. In terms of foaming capacity, only a small amount of foaming agent is required to generate delicate, stable foam cells that will not collapse during curing, lowering auxiliary material costs and making finished gloves lightweight and breathable to relieve hand fatigue for long-hour workers. Besides, this latex has wide adaptability, matching fully automated high-speed dipping lines and semi-manual small-scale equipment, and works well with cotton, polyester and blended fabric liners. Few formula adjustments are needed when switching raw material suppliers, and full stirring before tank filling ensures consistent coating thickness on every glove.

Fabric-supported gloves made from RFA-7631 have obvious market selling points for distributors and industrial buyers. Carboxyl groups on the copolymer chain increase crosslink density after vulcanization, significantly enhancing abrasion resistance. The coating can withstand repeated friction with metal scraps, rough concrete and sharp hardware, extending glove service life and cutting enterprises’ regular PPE procurement expenses. Meanwhile, optimized butadiene segments retain excellent film elasticity, so finished gloves stay supple and flexible, maintaining complete finger mobility and precise tactile sense for tool operation and delicate assembly work. As fully synthetic NBR latex without natural rubber proteins, it thoroughly eliminates Type I latex allergy risks, helping manufacturers meet strict international occupational health standards for large corporate clients. It also provides reliable barrier performance against machine grease, motor oil and mild industrial detergents, far outperforming natural rubber gloves in oily working environments.

Ruico releases complete standardized packaging, storage and safe handling rules to fully protect RFA-7631’s quality throughout the supply chain. Two bulk packaging types are available: Flexitank and IBC tank. Sealed unopened containers contain microbial inhibitors to resist mold and bacteria during transportation and storage, with a six-month shelf life in cool, dark warehouses. Freezing is strictly forbidden, as low temperatures will irreversibly damage the latex colloidal structure and waste entire batches. Once packaging is opened or latex is mixed with auxiliaries, factories must strengthen hygiene management of mixing barrels and dipping tanks, and supplementary biocides are recommended to prevent microbial contamination that leads to coating discoloration and film defects. All operators must follow safety guidelines in Ruico’s updated SDS documents. Direct eye contact and long-time skin exposure to concentrated latex should be avoided, and large-batch mixing must be carried out in fully ventilated workshops. Spilled latex creates slippery ground, so absorbent cleaning supplies and anti-slip mats are necessary safety equipment in all production zones.

Ruico offers full-cycle professional technical support to every cooperative manufacturer. Since finished glove quality depends on each factory’s unique production craft, fabric substrates, curing temperatures and customized formulas, Ruico requires customers to carry out multiple small trial tests according to local certification standards before mass production to avoid massive defective products. Professional technical engineers provide remote consultation or on-site troubleshooting for compounding instability, uneven coating and foaming defects. Clients can reach Ruico’s Huzhou headquarters via phone, fax, email or official website to request the latest SDS, formulation guides or arrange factory visits and sample testing.

For glove factories eager to reduce raw material waste, simplify compounding procedures and launch differentiated high-quality fabric-supported gloves, RFA-7631 is a trustworthy integrated carboxylated NBR latex solution. It cuts overall manufacturing costs while producing hypoallergenic, durable and soft gloves favored by industrial end users. Supported by rigorous chemical storage safety specifications and responsive end-to-end technical service from Zhejiang Ruico Advanced Materials, RFA-7631 has become a preferred core raw material for modern PPE factories pursuing stable output and stronger market competitiveness.
