TPX™ MLL411 by Mitsui Chemicals is an opaque, heat resistant, low density polymethylpentene. Possible applications include food containers, release film for FPC, rubber hoses and release paper for synthetic leather. It boasts superior releasability and is one of the lightest polymer materials among thermoplastic plastics. It is also suitable for animal cage, resin modification, LED mold, experimental apparatuses and hollow fiber. Exhibits gas permeability, low refractive index, low dielectric property and high insulation properties equivalent to fluororesin. Offers excellent chemical & steam resistance and high durability against acid, alkali and alcohol. Recommended for processing by mandrel, pipe and profile type extrusion. TPX™ MLL411 shows excellent transparency equivalent to glass and acrylic as well as high melting point and can be used at high temperature.
