Q:What's the raw tape?

A white, opaque, membranous, polytetrafluoroethylene product, used as a supplement in plumbing and plumbing. Chemical name is PTFE, the product name is "PTFE" - raw tape. Raw rubber tape is PTFE - the commonly known as raw meal belt. The raw rubber tape is mainly used for the interface of hot and cold water supply pipe fittings, so as to enhance the tightness of the pipe connection, prevent the interface from leaking, and increase the leak proof function of the interface. At present, sanitary tapes are used in HVAC and water supply and drainage.

Q:What are the weights for profiled steel sheet roofing, spunbond polyethylene and polypropylene waterproof and breathable?

Polyethylene film is a commonly used plastic film, because of its non-toxic, so a lot of food used for making packaging bags. Notice the difference between PVC and polyvinyl chloride (PVC). The simple way is to make the polyethylene film for ignition, and the non flammable is PVC film.A separation layer between a polyethylene film, a barrier layer, an intervening coil, and concrete or other protective layer. It is also considered a separate protective layer.

Q:PVC pipe and duct tape tape what is the difference

First，PVC pipe adhesive tape:PVC pipeline adhesive tape is the base material, PVC material, trade name: anticorrosion tape, pipeline anticorrosion tape

Q:What's the quota for PE membrane isolation layer?

1.2 thick polyethylene geomembrane fixed: Materials 15 yuan / square meter, artificial 4 yuan / square meter.

Q:How many or how many hours can the scotch tape decompose?

The mechanical strength and electrical insulation are good, but its heat resistance is poor, softening point is 80 degrees, at 130 degrees, began to decompose, change color, and precipitation of HCI (chemical substances)

Q:What material is the base material of PVC electric tape?

Specializing in the production of high temperature adhesive tape, electrical tape, color electrical tape, PVC color mark tape, PVC mark tape, PVC pipeline adhesive tape and other kinds of tape

Q:Why are bare wires tied with black tape?

Black tape is often referred to as "PVC" adhesive tape, which ties bare wires because of the electrical insulation properties of the PVC electrical tape.

Q:What's the difference between waterproof tape and PVC tape?

[] refers to electrical insulating tape insulation tape used to prevent leakage, insulation tape. Also known as insulating tape, adhesive tape, composed of baseband and pressure-sensitive adhesive layer. The base band is made of cotton fabric, synthetic fiber fabric and plastic film. The adhesive layer is made of rubber and tackifier. It has good adhesion and good insulation. Insulating tape has good insulation, pressure resistance, flame retardant, weather resistance and other characteristics. It is suitable for wire feeder, electrical insulation protection and so on.

Q:Theoretical dosage of polyethylene anticorrosion insulating tape

Anticorrosion tape dosage = pipe surface area * (1+5%)5% is theoretical loss

Q:What is PVC double sided tape?

PVC double-sided tape, mainly refers to the PVC membrane as the substrate double-sided tape, double-sided coated elastomer pressure-sensitive adhesive or resin adhesive, acrylic pressure-sensitive adhesive, adhesive prepared on the PVC substrate with rolls or sheets.
