Description

Premium Polyvinyl Butyral (PVB) Resin Powder - High-Performance Binder for Safety Glass, Coatings, and Advanced Composites! Unleash the power of pure polyvinyl butyral (PVB) resin – the gold-standard thermoplastic polymer renowned for its exceptional adhesion, optical clarity, and impact resistance. This fine white powder (CAS 63148-65-2) transforms into a flexible, transparent film when plasticized, making it the backbone of laminated safety glass worldwide. Lab-grade purity (≥99%) ensures consistent molecular weight and hydroxyl content for flawless processing in automotive, architectural, and industrial applications. Whether you're crafting bulletproof windshields or high-strength composites, our PVB delivers unmatched toughness and versatility – elevate your formulations today! Key Features & Specifications: Purity & Grade : ≥99% (industrial/pharma-grade); hydroxyl content 18–21%; butyral content 76–82%; acetate content ≤2%. Molecular Weight : 30,000–250,000 g/mol (customizable grades); viscosity (10% in ethanol) 20–80 mPa·s. Physical Properties : Fine white powder; density 1.08–1.10 g/cm³; glass transition temperature (Tg) ~70°C; highly soluble in alcohols, ketones, esters; insoluble in water. Thermal Stability : Softening point 140–170°C; decomposition >250°C; excellent UV and weather resistance. Optical Clarity : ≥90% light transmission when plasticized; refractive index ~1.49. Key Uses and Benefits: Laminated Safety Glass Mastery : Primary interlayer in automotive windshields, architectural glazing, and bullet-resistant panels – absorbs impact energy, prevents shattering, and maintains optical clarity even under extreme stress. Paints, Inks & Coatings : High-adhesion binder for wash primers, metal coatings, and printing inks – enhances corrosion resistance, flexibility, and pigment dispersion on steel, aluminum, and plastics. Adhesives & Sealants : Thermoplastic hot-melt component for wood, metal, and ceramic bonding – provides strong, flexible joints with excellent moisture resistance. Ceramics & Composites : Temporary binder in tape casting and green-body forming – burns out cleanly during sintering, leaving no residue in advanced ceramics and composites. Photovoltaic Encapsulants : Emerging use in solar panel lamination – offers superior UV stability and electrical insulation compared to EVA. Textiles & Nonwovens : Film-forming agent for fiber finishing and fabric coatings – improves tear strength and wash fastness. Why Choose Our PVB Resin? Tailored Grades : From low-viscosity (coatings) to high-molecular-weight (safety glass) – match your exact process needs. Global Standard : Meets ASTM F1642, EN ISO 12543, and ANSI Z97.1 for safety glazing. Safety First : Low toxicity but dust may irritate eyes/respiratory tract – use PPE (gloves, mask, goggles) during handling. Avoid inhalation and open flames (flammable dust hazard). Store in cool, dry, ventilated area away from strong oxidizers. Not for direct food/medical implant use without certification. Consult SDS for full handling protocols.
