PROCESS FOR PREPARING HMA HAVING A TACK-FREE COATING

The present invention relates to a process for preparing hot melt adhesive (HMA), preferably hot melt pressure sens itive adhesive (HMPSA), having a substantially tack-free coating, wherein said HMA, preferably HMPSA, can be easily handled, packed and transported for further use.

METHOD FOR REMOVING MOLD RELEASE AGENT AND TIRE
20170080608 · 2017-03-23 · ·

A method for efficiently and completely removing a mold release agent adhering to a tire surface after a cure-molding process. In this method, the mold release agent is removed from an adherend region where an adherend is to be affixed to the tire surface after cure-molding. A laser light having an intensity capable of removing rubber on the tire surface in the adherend region is intermittently irradiated while it is moved along. Thus a plurality of dents are formed in the adherend region in such a manner that the adjoining dents have their edges overlapped with each other.

20170057123 · 2017-03-02 ·

Provided is a method for manufacturing a roll-shaped mold wherein a mold release agent layer is formed on a mold body. A mold release agent solution is supplied from a mold release agent-discharging nozzle towards the mold body to adhere the mold release agent solution on the mold body. A gas is discharged from a gas-discharging nozzle toward the mold release agent solution adhering to the mold body to dry the mold release agent solution and form the mold release agent layer.

Processes and compositions for injection blow molding

The invention provides a process for injection blow molding an article, said process comprising injecting into a mold cavity a composition, comprising at least one ethylene-based polymer and less than, or equal to, 1000 ppm of a mold release agent, based on the total weight of the composition. The invention also provides a composition comprising a blend, wherein the blend comprises at least one high molecular weight (HMW) ethylene-based polymer, and at least one low molecular weight (LMW) ethylene-based polymer, and wherein the blend has an unsaturation level, as determined by IR, and expressed as vinyls per 1000 carbon atoms, less than, or equal to, 0.5 vinyls per 1000 carbon atoms, and wherein the high molecular weight (HMW) ethylene-based polymer has a density from 0.925 to 0.950 g/cc.

IN-SITU INJECTION MOLDED FASTENER CAP SEAL ENABLING HIGH PRODUCTION RATE AND BETTER QUALITY
20170036381 · 2017-02-09 ·

A method for sealing a fastener employs a mold which provided with an inlet port for molding material. The mold is then positioned over a fastener and the mold is sealed against a structure. A moisture cured polyurethane reactive adhesive (MCRPA) as a molding material is then heated and injected into the mold. Upon solidification of the MCRPA, the mold is then removed to expose the MCRPA to atmospheric moisture and cured to leave an in-situ molded cap formed over the fastener and sealed to the structure.

A control rod for incorporation into a composite assembly with at least a first composite preform, a second composite preform, and a cured resin includes a shaft defining an axis, wherein the shaft is disposable within an aperture in the composite assembly, and a plurality of threads disposed on at least a portion of the shaft. The shaft is made from, among other materials, a thermoplastic material. The threads define a thread pitch that encompasses more than one individual fiber layer forming at least one of the first composite layer and the second composite layer.

COMPOSITE WHEEL WITH FIBER-REINFORCED MOLDING COMPOUND HAVING MULTIPLE RESIN CHEMISTRIES, AND METHOD
20250256466 · 2025-08-14 ·

A composite wheel structure is made from a fiber-reinforced molding compound (FRMC) material having different resins at different axial sections of the wheel. The FRMC material can be provided as a roll of material, with different resin chemistries at different lateral sections, and applied to a wheel mold such that the different resin chemistries are provided at different axial sections. A single carrier film may have different resin chemistries at different sections, and chopped reinforcement fibers can be deposited across the width of the film. Multiple separate carrier films with different resin chemistries can be arranged side by side, and the chopped fibers added to the combined width. Reinforcing material can be provided in a prepreg and chopped and added to single carrier film at different width sections. The chopped fibers and different resins can be impregnated together to define the multi-resin FRMC material for use in the wheel layup.
