Abstract: Provided is a composite resin composition for automotive interior materials and an automotive interior material including the same. The composite resin composition comprises: 47 to 52 wt % of a polybutylene terephthalate resin; 10 to 28 wt % of a (meth)acrylate compound-conjugated diene compound-aromatic vinyl compound copolymer; 8 to 14 wt % of a polyethylene terephthalate resin; 0.1 to 2.2 wt % of a carboxy reactive epoxy resin; and 10 to 28 wt % of glass fiber containing SiO2, CaO, and Al2O3, wherein an SiO2 content is greater than a sum of a CaO content and an Al2O3 content. By changing conventional components, the composite resin composition for automotive interior materials provided herein has an effect of improving heat resistance, impact stability, and crystallization rate controllability, satisfying physical property balance between mechanical properties and fluidity, and providing excellent product reliability and appearance.

Abstract: A process for producing PU foams, preferably flexible PU foams, can be performed by reacting at least one polyol component, comprising a recycled polyol, with at least one isocyanate component in the presence of one or more catalysts that catalyse the isocyanate-polyol and/or isocyanate-water reactions and/or isocyanate trimerization. The recycled polyol is obtained by hydrolysis of a polyurethane, by contacting said polyurethane with water in the presence of a specific base-catalyst-combination.

Abstract: A formulation for rubber composition with reduced odor and good thermal oxidative aging-resistance and tension fatigue resistance comprising 100 parts by weight of a diene elastomer, 30 to 70 parts by weight of a reinforcing filler, 0.1 to 8 parts by weight of an antidegradant composition, and 0.5 to 3 parts by weight of a crosslinker, wherein the antidegradant composition includes a 6PPD antidegradant with a purity of equal to or greater than about 98% and an S-TMQ. The rubber composition has no added odor inhibitor/adsorbent or deodorizing additive, while by using combination of 6PPD with purity of equal to or greater than about 98% and an S-TMQ instead of traditional combination of 6PPD and a TMQ, the VOC emission of the rubber composition is effectively reduced, the odor grade is reduced, and the thermal oxidative aging-resistance and tension fatigue resistance is improved.
