NEW fluoro polymer laminating technology being introduced to Australia by Dotmar EPP enables plant engineers to extract remarkable performance from materials handling surfaces ranging from conveyor and oven belts to trays, processing tables and chemical tanks.<[etk]>
The Chemlam multi-laminar process marries coated textile reinforcing materials with cast multi-layer fluoro polymer films to produce light, durable and non-toxic surfaces engineered for low friction, easy release and non-stick performance combining low chemical and grease permeability with outstanding heat transfer properties.
The superior mechanical properties produced by Chemlam means thinner materials can be used in many applications where high-performance coatings have been applied to substrate bases including woven fibreglass, fibreglass, aramids and specialty substrates.
The coatings are built up in layers (similar to multiple dipping of a candle) to produce crack and pinhole-free surfaces suitable for applications ranging from food, beverage, chemical and plastics processing and packaging to energy, environmental and protective systems requiring low chemical permeation, easy decontamination, flame resistance and outdoor durability.
“The lack of cracks and pinholes offer many important benefits, including ease of cleaning, because there are no anchor points for contaminates. And because the laminates protect their reinforcement materials better, the belt or surface retains its mechanical properties longer” Dotmar EPP engineer Lance Bergroth said.
Each layer of the coating can be modified for specific properties, such as hardened surfaces, special colours and different polymers. The process can also join materials that are normally incompatible.
“Benefits of the process include higher tear and tensile strength, higher product throughput because of quicker processing cycles and energy savings because platen temperatures can be lowered as a result of the better heat transfer qualities of the thinner materials” Bergroth said.
“As a heat-resistant conveying or sealing material, a Chemlam product is effective over a wide temperature band ranging from –150°C to 260°C, therefore providing long-term benefits.”
