Principle release agent

Plastic mold release is a release agent, a release agent specifically for the plastics industry, the characteristics of custom, high temperature. It can improve the strength and heat resistance of the plastic mold release agent, and reduce costs. Such as phenolic resin after adding flour can greatly reduce costs and make Bakelite became one of the cheapest plastic, as well as significantly improve the mechanical strength.
Fillers can be divided into organic fillers and inorganic fillers. The former such as wood flour, rags, paper and various textile fibers, such as glass fiber which, diatomaceous earth, asbestos, carbon black and the like.
Mold temperature is too low, the fuel injection pressure is low. Contraction: the cooling time is short, injection pressure, low exhaust poor.
Batch Peak: injection too much pressure, high temperature, mold aging or wear. Deformation: short molding time, too much packaging, thimble uneven thickness, uneven shape of the product. 5.
The line: mold temperature is too low, too raw, too much mixing times wiping release agent.
Most plastic release agent chemical stability, light weight, no rust, impact resistance; has good transparency, abrasion resistance; good insulation, low thermal conductivity; in fact, resin and plastic are two different concept. A raw polymer resin is raw, it is not only used to make plastics, but also paints, adhesives and synthetic raw materials. In addition to a tiny percentage of the plastic resin containing 100 percent, but some of the plastic release agent dissolved in a solvent. Thermoplastic: thermosetting plastic releasing agent heating means other conditions can be cured or insurmountable (melting plastic release agent) features, such as bakelite, epoxy plastic release agent.
Thermosetting plastic mold release formaldehyde cross-linking was divided, and other cross-linking two. Formaldehyde-crosslinked plastic mold release agents include Bakelite, plastic mold release amino urea (formaldehyde, melamine-formaldehyde, etc.). Other cross-linked plastic release agent comprises: an unsaturated polyester, epoxy resin, phthalic diallyl resin. Thermoset: thermoplastic plastic release agent refers to a specific temperature range, which can soften and cold (hot) multiple sclerosis plastic release agent, such as polyethylene.
Polytetrafluoroethylene (Ptfe) and the like. Thermoplastic mold release also contains hydrocarbons divisive polarity genes. Vinyl. Project.
Cellulose and the like. Various types. During the drying process, moisture meter measured continuously and instantly displays the sample moisture content% loss, after the drying process is complete, the plastic mold release high frequency plastic welding machine welding machine is the preferred release agent plastic heat sealing equipment. The main principle amount and the interest will be high field repeatedly reversed plastic polar molecules to generate friction heat, thus achieving the purpose of welding, the welding temperature is uniform table. Any PVC content> 10% of the plastic material sheet, regardless of their hardware and software, can be combined with a high frequency plastic heat sealing machine heat. Final determination of moisture content value is locked display. General formability, good, low cost, coloring, poor dimensional stability, easy deformation; most poor heat resistance plastic mold release agents, thermal expansion of combustion; most plastics release agent poor low temperature resistance, low temperature brittle, easily aging. Such as polyvinyl chloride resin and PVC, phenolic resins and phenolic confused.
