WebPPS resins (base polymer, glass-reinforced, and mineral/glass-reinforced systems) are typically used for injection molding, extrusion blow molding, and extrusion applications. Polyphenylene Sulfide can be processed at temperatures in the range of 300 to 350°C. The processing of PPS can be hampered at times due to its high melting point. WebThe main resin characteristics are listed in Table 1. Figure 2 shows the pH working ranges of the ion exchangers as titration curves (using sodium hydroxide), that is, the pH ranges over which the functional groups are charged.

WebFeb 25, 2024 · Top-coating epoxies are usually a 1:1 ratio, and are often a medium to high viscosity, but some of the softer curing ones are low-medium viscosity. Thicker (medium to high) viscosity resins are great for doming. Top-coating resins have various cure times averaging from 12 - 24 hours depending on brand and volume used. Webepoxy resin is a two component transparent epoxy resin/hardener system with the trade name L385:340 fom Martin G. Scheuffler.
