In the high-end industrial fields such as PVC rubber and plastic processing, automotive interiors, wires and cables, eco-friendly plasticizers with low volatility, low fogging, weather resistance and heat resistance have become core raw materials for manufacturing high-quality products. Dipropylheptyl Phthalate (DPHP) is a new type of phthalate plasticizer with excellent comprehensive performance. With a stable physical and chemical structure and outstanding processing adaptability, it perfectly replaces traditional general plasticizers and becomes a preferred additive for the production of medium and high-end rubber and plastic products.
Low volatility plasticizer is the core advantage of DPHP. Compared with traditional plasticizers such as DOP and DBP, DPHP has a more stable molecular structure with extremely low volatilization during high-temperature processing and long-term service. It produces little smoke and odor during production, greatly improving the workshop processing environment. Meanwhile, it effectively prevents the hardening, shrinkage and performance attenuation of plastic products caused by additive volatilization, significantly extending the service life and stability of finished products.
Meeting the strict testing standards of the automotive interior industry, DPHP features outstanding low fogging performance. Automotive interior plastic parts are often exposed to high temperature, sunlight exposure and closed environments. Ordinary plasticizers are prone to volatilization and fogging, forming a haze film on car windows and affecting driving safety. With an ultra-low fogging rate, DPHP completely avoids the fogging problem and fully meets the high-end quality inspection requirements of automotive interior products, making it an essential additive for automotive floor mats, interior plates and sealing plastic parts.
As a professional wire and cable grade plasticizer, DPHP possesses excellent insulation properties and processing toughness. PVC cable materials modified with DPHP have good flexibility and anti-migration performance, resisting brittle fracture at low temperatures and aging at high temperatures. It can stably maintain the insulation and protection performance of cables, suitable for civil wires, industrial control cables, home decoration sheath cables and other scenarios, balancing processing efficiency and finished product safety.
In addition, DPHP acts as a premium heat & weather resistant PVC additive with excellent high-temperature resistance, low-temperature resistance, anti-aging and weather resistance. Facing complex working conditions such as outdoor exposure, temperature alternation and humid environments, PVC products blended with DPHP are not easy to yellow, crack or fail, and can maintain stable mechanical properties and appearance for a long time. It is widely used in outdoor plastic pipes, sealing accessories, outdoor cable sheaths, high-end artificial leather and other products.
In summary, DPHP integrates multiple advantages including low volatility, low fogging, heat and weather resistance, and environmental stability, serving multiple high-end fields such as automobiles, wires and cables, outdoor rubber and plastic products, and high-end PVC goods.
