Description：

Material of PTFE Sewing Thread：

Polytetrafluoroethylene resin, a unique substance, is the only ingredient in PTFE sewing thread. This material has many exceptional qualities, such as resistance to hydrolysis, oxidation, corrosion, and high temperatures (-196 to 260°C).

100% PTFE resin from Dupont or Dakin.

Features of PTFE sewing thread：

Excellent high temperature resistance: Polytetrafluoroethylene (PTFE) is capable of withstanding temperatures as high as 220°C for prolonged periods of time without melting or breaking down.
Chemical resistance: PTFE can be used safely in chemically corrosive environments because it exhibits good corrosion resistance to the majority of chemicals.

Wear resistance: PTFE sewing thread resists wear and breaks less readily than other threads because of its high wear resistance.

Tensile strength: PTFE sewing thread is appropriate for sewing objects that must endure high tensile forces because it typically has a high tensile strength.

Food industry: PTFE sewing thread is a non-toxic material that does not release harmful substances and is thus appropriate for sewing food processing equipment. The material's unique properties make it perfect for use in the food processing industry, where safety and hygiene are of paramount importance. The thread's non-toxic nature ensures that it does not contaminate food products and does not release harmful chemicals or substances when exposed to high temperatures or harsh conditions. PTFE sewing thread is commonly used to sew food processing equipment like mixing tanks, conveyor belts, and other machinery used in food processing factories. Using PTFE color sewing thread in the food processing industry ensures that the sewn equipment remains durable and can withstand harsh conditions, resulting in an extended equipment lifespan and reducing the need for frequent repairs or replacements.

Application of PTFE sewing thread：

Filter bag: PTFE sewing thread is a popular choice for sewing dust filter bags made of various materials, such as fiberglass, PPS, Nomex, P84, and others. These filter bags are used by many industries to collect and eliminate dust, particles, and other pollutants. The superior temperature and chemical resistance of PTFE sewing thread makes it an excellent choice for ensuring the longevity and effectiveness of these filter bags.

Sports goods & sun protections: Excellent for outdoor use, PTFE sewing thread meets industry standards and is used for shade sails, large structural awnings, car umbrellas, patio furniture, marine canvas, and boat covers. It resists rot, mildew, chemicals, weather, and UV radiation damage.

Sewing in high-temperature environments: PTFE sewing thread is an excellent choice for sewing in high-temperature environments, This PTFE sewing thread can withstand temperatures ranging from -196 to 260℃, making it ideal for high-temperature processes. Additionally, the material's exceptional resistance to corrosion, hydrolysis, and oxidation makes it perfect for use in high-temperature environments. Using PTFE Color sewing thread ensures that the sewn objects or equipment are durable and can withstand harsh manufacturing environments.

Chemical industry: The chemical industry frequently uses PTFE Color sewing thread to sew equipment or containers that require contact with corrosive chemicals.
