Patented Chlorinated Ester for Flame Retardant Plasticization
DoverGuard® E-35 is a patented chlorinated ester designed for use as a secondary flame retardant plasticizer in PVC and other industrial applications. Developed as a cost-effective alternative to traditional phosphates, phthalates, and chlorinated paraffins, DoverGuard E-35 delivers improved compatibility, enhanced processing efficiency, and increased formulation efficiency.
DoverGuard E-35 combines flame retardant performance, plasticization benefits, and sustainability advantages in a single patented technology. The product helps formulators improve performance while reducing reliance on traditional plasticizers and flame retardant additives.
DoverGuard E-35 is used in applications where formulators require a combination of flame retardancy, plasticization, processing efficiency, and sustainability performance. Its unique chemistry supports a broad range of plastics and industrial formulations.
DoverGuard E-35 is a patented chlorinated ester technology developed to provide formulators with a versatile alternative to conventional plasticizers and flame retardant additives. The product functions as a secondary flame retardant plasticizer while improving compatibility, processing performance, and formulation efficiency.
Unlike traditional phthalates, phosphates, and chlorinated paraffins, DoverGuard E-35 combines performance and sustainability advantages in a single solution. Its low volatility, reduced water extractability, improved flexibility, and lower plastisol viscosity make it an attractive option for manufacturers seeking enhanced product performance and regulatory confidence.
DoverGuard E-35 functions as both a secondary flame retardant and a plasticizer, helping formulators improve fire resistance while maintaining flexibility and processing performance. Its chlorinated ester chemistry enables efficient incorporation into PVC and related formulations.
DoverGuard E-35 is readily biodegradable, based on sustainable raw materials, and is not considered a Substance of Very High Concern (SVHC). The product is not listed on California Proposition 65 and has been reviewed by the U.S. EPA for use in plastics and metalworking applications.
DoverGuard E-35 can serve as a cost-effective alternative to phosphates, phthalates, and chlorinated paraffins in many applications. The technology offers lower volatility, lower water extractability, increased flex strength, and reduced plastisol viscosity while supporting improved formulation efficiency.
