Fill materials are used to fill in missing parts or breaks in a ceramic piece in order to stabilize the piece. A wide range of materials and techniques have been used to restore losses in ceramics. Today the most common filling materials are made from calcium-sulphate-based fillers or synthetic resins such as epoxy, acrylic, or polyester resin.
Car mouldings include side body moulding, lower body moulding, door moldings, window mouldings, footrest moulding, [1] mudflaps, etc. They are often found in services in association with car mats, etc. Various car mouldings must have high scratch resistance, weather resistance and gloss matching that of the car body.
Trivalent chromium plating, also known as tri-chrome, Cr 3+, and chrome(III) plating, uses chromium sulfate or chromium chloride as the main ingredient. Trivalent chromium plating is an alternative to hexavalent chromium in certain applications and thicknesses (e.g. decorative plating). [2]
Vacuum Assisted Resin Transfer Molding (VARTM) or Vacuum Injected Molding (VIM) is a closed mold, out of autoclave (OOA) [1] composite manufacturing process. VARTM is a variation of Resin Transfer Molding (RTM) with its distinguishing characteristic being the replacement of the top portion of a mold tool with a vacuum bag and the use of a vacuum to assist in resin flow.

Polyolefins such as polyethylene and polypropylene are susceptible to photo-oxidation and around 70% of light stabilizers produced world-wide are used in their protection, despite them representing only around 50% of global plastic production. [1]
MDF (medium-density fiberboard) is a common material used for baseboard trim and molding. It is an engineered wood product manufactured from refined wood fibers combined with wax and resin binders. MDF is denser and more rigid than standard particle board. Compared to solid wood trim, MDF baseboard has the advantage of being consistent in ...
Compression molding is a method of molding in which the molding material, generally preheated, is first placed in an open, heated mold cavity. The mold is closed with a top force or plug member, pressure is applied to force the material into contact with all mold areas, while heat and pressure are maintained until the molding material has cured; this process is known as compression molding ...
Reaction injection molding (RIM) is similar to injection molding except thermosetting polymers are used, which requires a curing reaction to occur within the mold. Common items made via RIM include automotive bumpers , air spoilers , and fenders .
