Custom Performance & Design
In house material compound capability and rich experience in PTFE filed can gull fill your PTFE project.
Fluoropolymer Lab Supplies
Recently the challenges of the chemical laboratory are complex and multi-faceted. In addition to meeting all the requirements, the material must be pure, stable, and safe.
Dechengwang uses high-performance and homogeneous density PTFE/TFM material for our chemical laboratory customers because of its outstanding technical properties, like chemical resistance and allows working temperatures up to 260 °C. The extremely anti-adhesive, smooth surface paired with the hydrophobic behavior ensures low cross-contamination and ease of cleaning.

Typical PTFE Teflon® Labware Products
PTFE Teflon® Breakers
PTFE is an organic chemical made by polymerizing tetrafluoroethylene in a water emulsion to prevent chain reactions, which we use to make our breakers, an essential PTFE labware product. Because it has a compact symmetrical structure of atoms that is exceedingly dense, the substantial carbon and fluorine bonds give a strong chemical coupling. This gave PTFE chemical and thermal stability, making it one of the most widely used compounds across all industries. It is used in a fluid separation PTFE vessel with a tubular conduit to facilitate the separation of liquids of different densities. These PTFE breakers are made of solid PTFE and will not damage the glass lining of the vessel nozzle or flange face. The Teflon Breakers will resist corrosion, abrasion, and wear.
PTFE Teflon® Bottles
Teflon® bottles are among our high-quality PTFE, PFA, and other fluoropolymer bottles, which are part of our Teflon labware products. Chemically and corrosion-resistant, and typically autoclavable, PTFE bottles can handle a wide range of solvents, acids, and bases that other resins can’t. Machine finished heavy wall, wide mouth air tight PTFE bottles with screw closure for easy cleaning. PTFE bottles are virtually impervious to chemical attack, with the exception of high-temperature fluorine-containing compounds and molten alkali metals. The temperature range for working is cryogenic to 260°C. Non-sticking.
PTFE Teflon® Vials
Chemically inert, non-contaminating, and thermally stable in the range of -200°C (390°F) to + 280°C (+536°F), PTFE vials are a good choice. The vials have a “very smooth” texture on the interior and outside, making it nearly impossible for anything to “stick” to them. Chemical compatibility is maximised with PTFE, PFA, and Teflon Vials. PFA, PTFE, and Teflon vials are frequently used to prepare and store a wide range of materials for sensitive assays. The inert qualities of Teflon allow for the most rigorous acidic sample preparations without danger of contaminating or adulterating the original sample material, and the smooth surface and high service temperature range make them excellent for use directly on a hot plate.
