FAQ

Use CHNV's PE-dedicated compound WPC lubricant. Its built-in anchoring coupling structure locks the lubricant molecules firmly within the substrate, with no oil migration or bloom after 72 hours of boiling at 98°C. It stays free of whitening and hazing during long-term outdoor use, fully solving the bloom problem on outdoor boards.

CHNV lubricant uses a two-in-one lubrication-plus-compatibilization formula, so no extra coupling agent is needed. It thoroughly wets and disperses the wood flour, strengthens the wood-flour/plastic interfacial bond, eliminates voids, delamination and pitting, and raises the board's impact strength.

CHNV WPC lubricant balances internal and external lubrication with a wide processing window, adapting well to all kinds of aging domestic extruders. Screw torque is more stable, die build-up slows dramatically, cleaning frequency is roughly halved, and downtime losses are reduced.

We do not recommend mixing. CHNV offers separate PE-dedicated and PVC-dedicated lubricants: the PE grade suits outdoor decking and railings, while the PVC grade suits foamed wall panels and indoor profiles. Using the right grade avoids lubrication imbalance and board yellowing.

CHNV supplies the Southeast Asian market directly from its own overseas production base, eliminating extra coupling-agent purchasing costs and lowering total additive cost. The product is designed for the region's high heat, humidity and salt spray, resisting heat, moisture and bloom, and comes with complete customs and testing documentation.

Simply choose CHNV's general-purpose weather-resistant PE compound lubricant. One additive system covers both sheltered indoor products and open-air outdoor boards, so switching later needs no reformulation, cutting formula-tuning costs.

It can be used with an external stabilizer, but pairing CHNV lubricant with our matching calcium-zinc stabilizer system gives the best compatibility, with no additive antagonism, effectively avoiding zinc burning, color deviation and accelerated aging.

The full lubricant range comes with RoHS, REACH and food-contact safety test reports, meeting compliance for typical outdoor building-material exports. For especially strict export standards, we can provide custom grades and dedicated test documentation.

CHNV's compound lubricant replaces two traditional raw materials (lubricant plus coupling agent) in a single product, reducing the number of additives to purchase and the dosing steps, streamlining the shop-floor batching process and saving both labor and warehousing costs.

CHNV lubricant tightens the bond between bamboo flour and resin, shrinks tiny internal gaps, lowers the board's water absorption, and reduces moisture ingress that breeds mold, with standout results in the rainy, humid climates of southern regions.

CHNV's low-migration calcium stearate series has extremely low molecular mobility and resists volatilization and bloom at high temperature, effectively controlling interior bloom and windshield fogging, with all indicators meeting whole-vehicle VOC test standards.

Calcium stearate improves the dispersion uniformity of glass fiber and powder fillers and enhances melt flow, so large parts mold out full and smooth. Combined with zinc stearate for stronger release, it reduces mold carbon build-up and lowers rework and scrap losses.

CHNV zinc stearate offers excellent release performance suited to thermoset compression molding, so parts release easily from the mold, reducing housing scratches and breakage and lowering downstream polishing and repair labor.

High-purity zinc stearate acts as a vulcanization activator that promotes full rubber crosslinking, improving elasticity and wear resistance. It disperses evenly during mixing and does not bloom in long-term heat and humidity, extending the service life of rubber parts.

CHNV stearates use a dust-free micro-bead granulation process with very low dust and uniform granules, giving stable automated dosing, a cleaner workshop environment, and compatibility with fully automated lines.

CHNV calcium stearate provides long-lasting thermal stability, neutralizing acidic impurities in the resin and withstanding 105°C for the long term. It resists scorching during processing, so the harness sheathing is less prone to yellowing and cracking over its service life.

CHNV zinc stearate has outstanding dispersing power that fully breaks up pigment powder, giving evenly colored masterbatch and installed parts free of color spots and deviation. For light-colored products, it can be compounded with calcium stearate.

CHNV produces stearates across the full industry chain, benchmarking high-end imported additives at a lower overall purchasing cost. We support small-batch sampling and provide complete automotive-industry environmental test reports, enabling low-cost domestic substitution.

The products carry a full set of SGS, RoHS 2.0 and automotive fogging test reports, meeting the environmental access requirements of major OEMs, and can be used directly in interior/exterior trim and new-energy component production.

They should not be freely mixed. For low-fogging interior products we recommend a specific calcium-zinc ratio; for rubber vulcanization, zinc stearate is the main component. We can provide a dedicated, standardized formulation plan based on your specific product.
