HEAT-RESISTANT CHLORINE-CONTAINING CROSSLINKED RESIN FORMED BODY AND ITS PRODUCTION METHOD, SILANE MASTERBATCH AND MASTERBATCH MIXTURE, AND HEAT-RESISTANT PRODUCT
A method of producing a heat-resistant chlorine-containing crosslinked resin formed body, formed from: Step (a) of melt-mixing, to a base resin containing a chlorinated polyethylene and a polyvinyl chloride and a plasticizer, an organic peroxide, an inorganic filler, and a silane coupling agent, at a specific ratio, at a temperature equal to or higher than a decomposition temperature of the organic peroxide; Step (b) of mixing a silane masterbatch obtained in Step (a) and a silanol condensation catalyst; and Step (c) of crosslinking by bringing a formed body obtained by Step (b) into contact with water; wherein, in Step (a), from 5 to 55 mass % of the plasticizer is contained in 100 mass % of the base resin to be used in the reaction with the silane coupling agent; the formed body produced therefrom; a silane masterbatch and a mixture thereof; and a heat resistant product.
Expanded thermoplastic polyurethane beads and preparation method and application thereof
The present invention relates to expanded thermoplastic polyurethane beads, a preparation method for same, and an application thereof. The expanded thermoplastic polyurethane beads consists of components of the following parts by weight: 100 parts of a thermoplastic polyurethane, 1-10 parts of a cell size stabilizer, and 1-35 parts of a melt viscosity modifier. The preparation method for the expanded thermoplastic polyurethane beads is also disclosed. The bead is produced by employing a volatile blowing agent to immerse the thermoplastic polyurethane, comprising the pore size stabilizer and the melt viscosity modifier, in an aqueous suspension, and is then followed by the foaming process. Utilization of the expanded thermoplastic polyurethane beads of the present invention allows for preparation of a foam product. The expanded thermoplastic polyurethane beads prepared per the present invention has uniform cell sizes and a high product yield. At the same time, the expanded thermoplastic polyurethane bead provides a great sintering performance even at a relatively low vapor pressure, a molded foam product has a small deformation, a low dimensional shrinkage ratio relative to a mold, great dimensional stability, and an aesthetically appealing appearance.
Solvent Cement Formulations
Provided are solvent cement formulations comprising some or all of tetrahydrofuran, cyclohexanone, methyl ethyl ketone, acetone, a thermoplastic resin, silica, and, a solvent soluble acrylic copolymer associative thickener. The disclosed formulations contain a reduced complement of volatile organic compounds (VOCs) relative to conventional cement formulations, yet are capable of meeting the requirements for regular-, medium-, and heavy-duty applications. The use of specialized associative thickener components confers a required degree of viscosity while enabling a reduction in the concentration of VOCs, such as tetrahydrofuran.
