SMC/BMC Resins

Principal Properties & Application: ALITA 1598 is an unsaturated polyester resin for SMC/BMC, made primarily from isophthalic acid and neopentyl glycol. It features high reactivity and thickening properties. It is used for injection/molding of BMC and SMC sheets, resulting in products with high mechanical strength, good electrical performance, and excellent heat and chemical resistance. It is applied in fields such[...]

Principal Properties & Application: ALITA 501 resin is a PTA-type unsaturated polyester resin, primarily made from purified terephthalic acid (PTA), maleic anhydride, and standard glycols. It is dissolved in a styrene crosslinking monomer, exhibiting high viscosity and high reactivity. ALITA 501 resin offers stable thickening, good strength and toughness, low shrinkage, and excellent water resistance. It is suitable for the[...]

Principal Properties & Application: ALITA L-5016 is a Low Profile (LP) additive specifically designed for Class-A surface SMC/BMC molding applications. Its exceptionally low viscosity and excellent shrinkage control enable the production of final products with precise shrinkage rates, including zero or even negative values. This makes it an ideal solution for compression molding of products requiring high surface quality[...]

Principal Properties & Application: ALITA 1506G resin is an unsaturated polyester resin primarily composed of phthalic anhydride and neopentyl glycol. It has high viscosity and reactivity. This versatile resin exhibits fast thickening, good flowability, and produces smooth, glossy surfaces. ALITA 1506G resin possesses excellent water resistance, heat resistance, high mechanical strength, and good electrical properties. It is widely used[...]

Principal Properties & Application: ALITA 1506 resin is a new pentanediol-based unsaturated polyester resin primarily derived from phthalic anhydride and neopentyl glycol. It has high viscosity and high reactivity. This high-performance resin thickens quickly, has good flowability, and exhibits excellent strength and toughness. ALITA 1506 resin is suitable for general SMC/BMC (Sheet Molding Compound/Bulk Molding Compound) products, making it[...]

Principal Properties & Application: ALITA 508B resin is an orthophthalic unsaturated polyester resin primarily made from phthalic anhydride. It has medium to high viscosity and high reactivity. ALITA 508B resin is used in Bulk Molding Compound (BMC) process, a compression molding resin technique, to effectively prevent issues like gas porosity. The products made with this high-performance resin have excellent[...]
