Filler materials are particles added to binders (resin, thermoplastics, cement) to make a composite material. Filler materials improve specific properties or make the product cheaper. [1] Coarse filler materials such as construction aggregate and rebar are used in the building industry to make plaster, mortar and concrete.
A expansion joint, or movement joint, is an assembly designed to hold parts together while safely absorbing temperature-induced expansion and contraction of building materials. They are commonly found between sections of buildings , bridges , sidewalks , railway tracks , piping systems , ships , and other structures.
The mixing is done at room temperature and stored at low temperatures to slow down curing prior to molding. The concentration of the mixture can vary depending on application, but is typically 30% glass fibers, 25% filler, and 45% resin, styrene, and initiator. [2] The material is provided in bulk or in logs approximately 4" in diameter.
Spiral-wound gaskets comprise a mix of metallic and filler material. [8] Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flexible graphite) wound in the same manner but starting from the opposing side. This results ...
FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). "FR" stands for "flame retardant", and does not denote that the material complies with the standard UL94V-0 unless testing is performed to UL 94, Vertical Flame testing in Section 8 at a compliant lab. The ...
Mineral wool is any fibrous material formed by spinning or drawing molten mineral or rock materials such as slag and ceramics. [1] Applications of mineral wool include thermal insulation (as both structural insulation and pipe insulation), filtration, soundproofing, and hydroponic growth medium.
4043 aluminium alloy [1] [2] [3] is a wrought aluminium alloy with good corrosion resistance typically used as filler material [4] [5] for welding of aluminium parts. It contains high amounts of silicon (between 4.5 and 6%) and trace amounts of other metals. [6]
Silicone rubbers are often one- or two-part polymers, and may contain fillers to improve properties or reduce cost. Silicone rubber is generally non-reactive, stable, and resistant to extreme environments and temperatures from −55 to 300 °C (−70 to 570 °F) while still maintaining its useful properties.
