Lucobit products are an extremely interesting and novel combination of proven materials used in the plastics processing industry. The material is black and consists of mixtures based on high quality polyethylene copolymers with varying additions of special and amorphous bitumen. Bitumen is integrated homogeneously in the polymer matrix and thus can be processed as free-flowing granules on conventional processing equipment. In the traditional application area "Sealing Membranes in Construction Building and Civil Engineering" Lucobit is well known as ECB (ethylene copolymer bitumen according to DIN 16729) and has proven to be a robust and reliable raw material for roofing and sealing membranes for the more than three decades.

Lucobit combines the positive properties of polyolefins and bitumen. When adding Bitumen to Lucobit it serves as a plasticizer and as an internal lubricant. Lucobit displays superior tenacity, biaxial stretchability, and flexibility even at low temperatures. Special stabilization provides excellent resistance against heat aging and UV radiation. Lucobit is not only resistant to weathering and ageing to a large extent, but also displays superior thermal stability.

Applications
Whenever the benefits of bitumen as a raw material shall be proven in the world of plastics, free-flowing Lucobit granules can be the technological solution. The main application areas in the plastics industry are:

• roofing and sealing membranes for: tunnels, land-fills, water retention basins, dikes

• profiles, e.g. waterstops, connecting profiles, etc. for the construction sector

• films for construction and civil engineering, laminating films, multi-layer films

• polymer modification of bitumen; bitumen modification of polymers

• robust, long-life injection moulded parts in the construction area, such as castors, shingles, fittings, and feet.

• coatings as corrosion protection, e.g. for pipes, steel and water tanks

• cable protection

• vibration damping, e.g. with profiles/bandages
