This year marks the 75th anniversary of the invention of PTFE, later named and trademarked as DuPont Teflon™. The "accidental invention" of Roy Plunkett, a DuPont chemist, is a fluoropolymer that is now used in virtually every manufacturing industry, service industry, military, and many medical applications.
It has become an essential part of our everyday lives in the most unassuming of ways. While researching new, safer chlorofluorocarbon refrigerants in 1938, Plunkett had tetrafluoroethylene gas stored in containers at dry-ice temperatures. When he opened a container, none of the gas came out. Instead, a white powder had formed inside, which was later found to be the polymer of tetrafluoroethylene (polyetrafluoroethylene), known today as Teflon™.
Further development of fluoropolymers included the discovery of these other widely used fluoropolymers, ETFE, PFA, and FEP. DuPont is still innovating today with their fluoropolymers.
The impact of Teflon™ is felt in most aspects of everyday life. Fluoropolymers are critical to new development in the fields of medicine, environmental conservation, energy solution, space exploration and civilian and military safety.

Perspex Frost is available in more than 20 colours in thickness of 3 mm, 6mm and 10mm.
It has a satin finish on both surfaces of the sheets thus minimising finger marks in display and shop fit outs where customers or staff regularly handle merchandise.
Perspex Frost can be cut, CNC routed, laser cut and bent by Allplastics for your next project or rollout.
The attached photo illustrates Perpex Frost Shirt displays in Violet Aurora 6mm thick which has been fabricated to customer specifications.

HDPE (PE300) has excellent impact strength, even at temperatures as low as -30º C. Coupled with its low coefficient of friction and ease of fabrication, HDPE is widely used in food, leisure and industrial applications.
Allplastics stocks and cuts a wide range of HDPE sheets and solid rods. We offer CNC Routing and CNC Machining Services as well as welding of tanks and trays.

Allplastics stocks a wide range of polypropylene Sheets and Rods.
Polypropylene is a highly chemical resistant polymer, lightweight and exhibits higher strength at higher temperatures than HDPE (Polyethylene)
It can be easily fabricated, formed & welded. This makes PP the ideal material for use in corrosion resistant applications.
PP exhibits good electrical properties and is non toxic for Food contact.
