FOAMABLE CHLORINATED VINYL CHLORIDE-BASED RESIN PARTICLES, FOAMED PARTICLES THEREOF, CHLORINATED VINYL CHLORIDE-BASED RESIN FOAM MOLDED ARTICLE, AND METHOD FOR PRODUCING FOAMABLE CHLORINATED VINYL CHLORIDE RESIN PARTICLES
Expandable chlorinated vinyl chloride-based resin particles from which a chlorinated vinyl chloride-based resin foamed molded product achieving both high expansion ratio and excellent surface appearance are provided. The expandable chlorinated vinyl chloride-based resin particles have a porosity of not more than 5.5 (ml/100 g).
SLIDING TENDONS FOR HIGH-STRAIN ELASTOMER ACTUATORS
A soft structure fiber reinforcement and actuation technology is provided. In an example embodiment, the tendon-driven, fiber-reinforced elastomer membrane comprises an elastomer matrix material and a fiber array embedded within the elastomer matrix material. The one or more tendons are not mechanically bonded to the elastomer matrix material, such that the one or more embedded tendons are able to move through the elastomer matrix material. One or more apparatuses may employ one or more such tendon-driven, fiber-reinforced elastomer membranes for use in a variety of applications.
METHODS FOR FORMING FOAMED BEADS INCLUDING A NANOSTRUCTURED FLUOROPOLYMER
A method for forming foamed beads includes: saturating pellets with a blowing agent to form saturated pellets; and depressurizing the saturated pellets in a pressure vessel to form the foamed beads. The pellets include: a matrix polymer component, and from 0.01 wt% to 2 wt%, based on the weight of the pellets, of a nanostructured fluoropolymer, a nanostructured fluoropolymer encapsulated by an encapsulating polymer, or a combination thereof.
FUNCTIONALIZED PROCESS AID BLENDS FOR CELLULAR PVC
A method of reducing foamed density that results in a foamed polyvinyl chloride (PVC) component exhibiting reduced density. The foamed PVC component contains at least a PVC resin and a process aid blend. The process aid blend contains from 1 weight % to 60 weight % (based on the weight of the blend) of a functionalized process aid, and from 99 weight % to 40 weight % (based on the weight of the blend) of a non-functionalized process aid. The functionalized process aid includes at least one base polymer functionalized with a reactive epoxy, hydroxyl, β-keto ester, β-keto amide, or carboxylic acid functional group. The foamed PVC component containing the process aid blend has a lower density than a reference foamed PVC component made using the same process conditions and additives, but which contains only non-functionalized process aid and not the functionalized process aid.
LAYERED BODY, MOLDED ARTICLE, PRINTED-WIRING BOARD AND ELECTROMAGNETIC WAVE SHIELD
A laminate that includes a substrate made of a polyolefin-based resin and is excellent in adhesion between the substrate and a metal plating layer is provided in a simple manner without roughening the surface of the substrate. In addition, a molded article, a printed wring board, and an electromagnetic wave shield using the laminate using the same are provided. Used is a laminate configured such that on a substrate (A) made of a polyolefin-based resin (a), a primer layer (B) containing a polyolefin-based resin (b) that is organic solvent soluble or water dispersible, a metal particle layer (C), and a metal plating layer (D) are sequentially laminated.

Disclosed herein too is a method comprising blending a primerless paint composition comprising a carboxylated chlorinated polyolefin elastomer; one or more of a polyacrylic binder, polyvinylchloride binder and a vinyl aromatic block copolymer binder; a pigment; and a liquid carrier; and disposing the primerless paint composition on a polyolefin elastomer substrate that does not have a primer disposed on it prior to the disposing of the primerless paint composition.
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.
CO-EXTRUSION SPC FOAM FLOORING AND MANUFACTURING METHOD THEREOF
A foam flooring includes a stone-plastic base material structure, which sequentially comprises, from top to bottom, a first stable layer, a foaming layer and a second stable layer. The first stable layer and the second stable layer are both sheets with a PVC resin and filler powder as main components, with 25-40 parts by mass of the PVC resin and 55-75 parts by mass of the filler powder; and the density of the SPC foam flooring is 1.4-1.6 g/cm3. The foaming layer is arranged between the two stable layers, such that the overall density of the flooring is significantly reduced and reaches 1.4-1.6 g/m3; since the foaming layer is arranged inside, the surface strength of the overall flooring is not influenced.
