3. Applicable fields: Infrastructure sealants for alpine regions, export sealants for photovoltaic HJT frame sealing.
1. Breakthrough content: New complete vacuum precision distillation equipment launched to produce dedicated high-purity electronic-grade VOS Liquid with active ingredient ≥99.2%; metallic impurities (Fe/Al/Ca) controlled at ppb levels (<50ppb), filling the domestic gap where VOS previously could not be used as semiconductor packaging auxiliary materials.
2. Supporting improvements: Batch purity fluctuation narrowed from ±1.2% to ±0.15%; overseas customer incoming inspection failure rate reduced from 8.7% to 0.4%.
3. Applicable fields: Electronic component potting adhesives for Europe and America, circuit board conformal coatings.
1. Breakthrough content: Elimination of gasoline-based organic solvent systems; closed-loop gas-phase ammonia neutralization process cuts product VOC emissions by 68%, complying with the new EU organic silicon auxiliary VOC control bill enacted in 2025. 100% resource recovery of by-product ammonium chloride solid waste, enabling full market access to the EU and UK.
2. Product performance improvement: VOS storage stability extended from the conventional 6 months to 12 months, with no layer separation or hydrolysis during transoceanic shipping.
3. Applicable fields: All EU/UK export silicone sealant and coating raw materials.
1. Breakthrough content: Directional modification of vinyl side chains. Silicones crosslinked with this product achieve a 35% improvement in adhesion to aluminum alloy and PP plastic substrates; peel strength rises from 1.2N/mm to 1.62N/mm, eliminating the need for additional titanate adhesion promoters in automotive body sealing formulas.
2. Cost optimization for downstream users: VOS dosage in downstream adhesive formulas can be reduced by 7%–9%.
3. Applicable fields: Automotive body sealing, general metal-plastic composite bonding sealants.
1. Breakthrough content: New catalytic hydrogenation closed-loop synthesis process cuts MEKO precipitation rate of finished products by 72% compared with conventional grades, meeting EU food-contact silicone raw material standards (EC1935/2004). No small molecule migration occurs after long-term high-temperature (120°C) baking of crosslinked silicone.
2. Performance upgrades: UV aging resistance optimized; matched sealants extend weather resistance service life from 15 years to 25 years.
3. Applications: Food machinery sealing in Europe and America, high-end curtain wall structural adhesives.
1. Breakthrough content: Fine-tuned molecular structure enables normal moisture crosslinking at -35°C, the first industrial-grade VOS applicable to polar wind turbine tower sealing. Crosslinking efficiency improves by 28% at equal dosage.
2. Key indicator: Product moisture content optimized from ≤150ppm to ≤40ppm, suitable for high-precision optical device packaging.
3. Applications: Polar wind power sealing, high-end optical component encapsulation.
1. Breakthrough content: Custom POE film-dedicated VOS grade maintains stability without hydrolysis after 1000h aging at 85°C / 85%RH. As a crosslinking additive for photovoltaic films, the yellowing index ΔE of films is less than 1.2 (industry standard ΔE ≥3.5).
2. Downstream optimization: Simplified overall adhesive formula without additional anti-hydrolysis auxiliary agents.
3. Applications: Photovoltaic module encapsulation films, solar panel edge sealants.
1. Breakthrough content: Deep MEKO removal refining technology reduces product odour grade from Level 3 to Level 1, with residual MEKO <0.15%, passing FDA medical auxiliary material certification. No volatile irritants are released during crosslinking of medical catheter silicone rubber.
2. Applications: Medical silicone catheters, implant device sealing materials.
1. Breakthrough content: Microchannel continuous synthesis yields products with purity ≥99.5% and single-batch impurity fluctuation <±0.05%, exclusively supplied to North American laboratories and high-end resin manufacturers. Raw material loss per ton of product reduced by 22%.
2. Applications: Laboratory organic synthesis, high-end electronic resin crosslinking additives.
1. Reduced compliance costs: Domestic low-free-MEKO VOS fully complies with REACH and new EU VOC regulations, eliminating secondary purification pretreatment after import. Batch customs inspection expenses are cut by 32%, and risks of EU customs detention are avoided.
2. Enhanced procurement flexibility: New domestic electronic-grade, food-grade and low-temperature special grades replace high-priced imported European and American materials, with unit purchase prices 18%–27% lower than imported equivalents of identical specifications.
3. Lower warehousing and logistics losses: Improved storage stability doubles shelf life on average; no deterioration or hydrolysis after 45 days of transoceanic shipping, enabling extended procurement stocking cycles and reduced split shipment freight costs.
1. Optimized formula production costs: Improved VOS crosslinking efficiency cuts average dosage by 6%–10%, reducing raw material costs by USD 120–220 per ton of finished adhesive. No extra adhesion or anti-hydrolysis additives required, trimming auxiliary material inventory categories.
