1. Superior Heat & Cold Resistance: WSD CHEMICAL's DOTP exhibits outstanding performance across a wide temperature range. It maintains flexibility at low temperatures and shows minimal weight loss at high temperatures, ensuring product longevity in both hot and cold climates.
2. Excellent Electrical Properties: With a volume resistivity significantly higher than conventional plasticizers, it is the preferred choice for high-quality, WSD CHEMICAL-recommended formulations in 70°C and 90°C rated cable insulation and sheathing compounds.
3. Low Volatility & Migration: Its linear molecular structure contributes to very low volatility and excellent resistance to extraction by oils, fats, and solvents. This translates to longer-lasting flexibility and reduced fogging in automotive interiors, a key benefit highlighted by WSD CHEMICAL for automotive applications.
4. Outstanding Compatibility & Plasticizing Efficiency: Offers excellent compatibility with PVC, vinyl chloride copolymers, and many synthetic rubbers. WSD CHEMICAL ensures its DOTP provides high plasticizing efficiency, resulting in soft, flexible compounds with good tensile strength and elongation.
5. Compliant & Sustainable Choice: Free from ortho-phthalates, WSD CHEMICAL's DOTP complies with major global regulations such as REACH, RoHS, and is suitable for sensitive applications, supporting your shift towards safer, more sustainable products.
