Provided is a molded body, including a polycarbonate-based resin composition containing: a polycarbonate-polyorganosiloxane copolymer (A); and at least one kind of compound (B) selected from the group consisting of an antioxidant, a dye, a release agent, a light-diffusing agent, a flame retardant, a UV absorber, a silicone-based compound, an epoxy compound, and a polyether compound, wherein the polycarbonate-polyorganosiloxane copolymer (A) contains a polycarbonate block (A-1) and a polyorganosiloxane block (A-2), and contains the polyorganosiloxane block (A-2) at a content of from 20 mass % to 70 mass %, and wherein the molded body has a durometer hardness of from 25 to 72, which is measured with a type D durometer in conformity with JIS K 6253-3:2012.

A gradient color massager includes a non-transparent core and a single-colored transparent cover wrapped around the outer surface of the non-transparent core. A vibrator is provided in the non-transparent core, and the thickness of each area of the outer surface of the single-colored transparent cover to the non-transparent core varies.

The present application relates to the technical field of a macromolecular material, and particularly to a creep-resistant fiber and a preparation method thereof. The creep-resistant fiber includes the following components: ultra-high molecular weight polyethylene, epoxy resin, graphene, nano-silicon carbide and mica. The preparation method thereof is that: S1. preparing an ultra-high molecular weight polyethylene fiber spinning solution; S2. swelling and performing extrusion spinning to obtain a filament; S3. after spinning, passing the filament through a spinneret plate, and shock cooling in a cold water bath; S4. preparing a crosslinking modification solution; S5. conducting ultrasonic extraction; S6. drying and hot stretching to obtain a creep-resistant ultra-high molecular weight polyethylene fiber.

A technique of manufacturing an elastomeric container closure or plunger with embedded functional components to avoid thermal damage to the components is described. The technique includes molding a drug-contacting part from a first material at a first temperature and for a first length of time defining a first thermal exposure; after molding the drug-contacting part, inserting ancillary components into the drug-contacting part, where the ancillary components have an operational thermal budget less than the first thermal exposure; and overmolding the drug-contracting part and the ancillary components with a second material at a second temperature for a second length of time to form a non-drug-contacting part that mechanically connects the non-drug-contacting part and the drug-contacting part to form the elastomeric container closure and seals the ancillary components inside the elastomeric container closure. The overmolding defines a thermal exposure less than the operational thermal budget of the ancillary components.

The invention provides a method producing contact lenses, comprising the step of: separating the mold into the male and female mold halves, with the silicone hydrogel contact lens adhered on one of the male and female mold halves; bring a shaped ultrasonic horn in direct contact with at least one area of a non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon; and applying a ultrasonic vibrational energy to the at least one area of the non-optical surface of the female mold half or the male mold half having the molded silicone hydrogel contact lens attached thereon so as to separate the molded silicone hydrogel contact lens from the mold half attached thereon.

More particularly, raw materials included in the composite resin composition for automobile interior products are optimized so that heat resistance and hydrolysis resistance stability are improved. Accordingly, the balance between physical properties such as mechanical properties and fluidity is satisfied and excellent product reliability and appearance can be provided.

A plant for producing an extruded silicone intermediate has a mixer/extruder for mixing and subsequently extruding a silicone compound for producing a raw silicone extrudate. A heating apparatus of the plant serves for crosslinking the raw extrudate to give the crosslinked silicone intermediate. The result is a plant with which a silicone intermediate of this kind can be produced more economically.
