Usage of ISODECYL DIPHENYL PHOSPHATE
1. Excellent low-temperature resistant plasticizer for multiple resin systems
DPDP shows outstanding compatibility with PVC, PVA, nitrocellulose, cellulose acetate butyrate, epoxy resin, phenolic resin and acrylic resin. Different from common phosphate plasticizers with poor cold resistance, it greatly improves the low-temperature toughness, ductility and flexibility of polymer materials. It effectively prevents plastic products from cracking, hardening and brittle failure under extreme low-temperature environments, perfectly suitable for cold-region PVC films, decorative sheets, wallpaper and outdoor plastic finished products.
2.Low-volatility & anti-migration additive for wire, cable and automotive interiors
Featuring extremely low volatility and excellent extraction resistance, DPDP will not migrate, precipitate or bloom on the product surface during long-term high-temperature use and aging tests. It maintains stable insulation performance, mechanical strength and perfect appearance of wire and cable sheath insulation layers. It fully meets the long-term durability and flame-retardant safety requirements of automotive interior plastic parts, indoor decorative materials and public transportation supporting materials.
3.Multifunctional modifier for coatings, adhesives and synthetic leather
DPDP can uniformly blend into water-based and oil-based coating and adhesive systems, optimizing film-forming performance and improving coating flexibility, adhesion strength and weather resistance. It effectively inhibits film peeling, aging and hardening caused by temperature fluctuation. Applied in synthetic leather and textile coating fabrics, it endows materials with soft hand feel, excellent folding resistance and lasting flame-retardant protection without affecting product texture and appearance.
4.Efficient synergistic flame retardant for plastic modification & masterbatch
It can be used independently or compounded with other halogen-free flame retardants to produce significant synergistic flame-retardant effects, effectively improving the oxygen index and fire rating of polymer materials. It enhances the overall processing stability and mechanical properties of modified plastics, avoiding the common defects of reduced toughness and easy brittleness caused by traditional flame retardants. Widely used in customized modification of various flame-retardant engineering plastics and soft plastic masterbatches.
5.Safe and stable fine chemical additive for high-end applications
DPDP is halogen-free, low-odor and environmentally friendly, with stable chemical properties and no harmful precipitation during use. It adapts to high-standard production requirements of civil decorative materials, building flame-retardant materials and transportation supporting plastic products, helping manufacturers produce low-carbon, safe and high weather-resistant flame-retardant finished products.
