FRP SMC material (Sheet moulding compond)
Sheet moulding compond FRP SMC material
Sheet Molding compound (SMC) is a mineral filled, fiberglass reinforced polyester (vinyl ester and phenolic) based molding compound. SMC is a thermosetting material that undergoes an irreversible cross-linking reaction when exposed to the heat and pressure of the thermoset molding process (i. e. Ambient delivery of material to a heated molding surface). A somewhat tacky, dough-like mass in its unmolded state, SMC is covered to an infusible, solid state using injection, compression and transfer methods.
SMC provides a competitive alternative to die cast and drawn metals, sheet molding products and engineering thermoplastics. Notable SMC properties include resistance to creep and discoloration when exposed to heat and load, notched impact performance, high modulus and surface durability(resistant to reagent/stain, chemical, scratch and ultra violet attack). SMC can be formulated to meet specific a performance profile, this unique customization allows for the elimination of costly additives and reinforcements where possible. This "cafeteria approach'' to material development sets SMC apart when evaluating price versus performance properties.
Question1: Are you a factory or sales company?
Answer1: Sure, we are a factory for supplying BMC&SMC products since the year of 1988.
Q2: How about your supplying ability?
A2: About 50, 000 Ton per year with 150 staffs as the year 2012.
Q3: What's your advantage?
A3: 1, we have lots of experience as 25 years in the SMC&BMC market, know clearly about the material performance and compositions.
2, we have many important certificates to suit our customers' market demands and also as a promise of our material quality, like the RoHS, UL, CCC, ISO9001, etc.
3, we, as a platform, understand the whole SMC&BMC market clearly from our cooperated native customer. We supply not only the material itself, but also lots of SMC&BMC products in our factories, such as manhole cover, electricity meter box, current breaker, water tank, bracket, helmet, etc.
Also we could do OEM/ODM order, Welcome to cooperate with us.
Q4: How to begin to cooperate with your factory?
A4: It depends on your demands, you could check on our website to find your required products, or send us your information about the product, so then we could find the suitable products in our list to get further step quickly...
Q5: What's your factory payment term?
A5: We could accept many kind of payment demands, the most way of our customer's payment as T/T, L/C, Paypal, West Union. If you have special demands on it, please feel free to ask.
Q6: Could we be an agent of your factory in our market?
A6: Yes, welcome to join us. The details should be checked by different markets.
Q7: Which country did you export?
