Hot melts and adhesives
Features and benefits of PTFE
- Ability to handle a wide temperature variance: -60⁰C to +260⁰C
- Not affected by heat aging
- Compatible with a very wide range of chemicals
- Low permeability rates
- Not affected by Ozone or UV exposure
- Low co-efficient of friction—better system efficiency due to lower pressure drops
- Non flammable
- Superior flex fatigue life
- Low volumetric expansion
Hot melt is a process where a polymer-based glue or adhesive is applied in its molten state by using a heated hose and a glue gun. The process is widely used to glue various parts together in industrial segments like packaging, furniture, bookbinding, carton-making, labels, product assembly and in the automotive industry.
The heated hose is made of a PTFE liner with layers built around of stainless steel (or textile) braid, silicon tape, a heating element, several layers of fiberglass isolation followed by a protective sleeve.
Due to its unique properties, PTFE is the perfect solution for this application. PTFE can handle a wide temperature range of up to 260°C/ 500°F and has the lowest coefficient of friction of any solid known; these properties, along with non-stick properties, ensure continuous low pressure drops with no blockage during service.
PTFE liners are highly resistant against a very wide range of chemicals and adhesives, do not age and maintain superior flex fatigue resistance.
