What are the ingredients of tape? Is it possible that formaldehyde is present?

What types of tapes and their characteristics and effects are detailed

Fully transparent tape: It is made of transparent PETBOPP plastic film as the base material, and double-sided dispensing modified acrylic polyurethane resin. It is made of white anti-stick paper treated with silicone material as isolation paper. It is thinner and evenly symmetrical than white cotton paper tape. It is fully transparent and unmoistered, has long-term adhesion, and it has very good moisture resistance, steam resistance, and ultraviolet rays and temperature resistance. It is mainly used for shoes and leather industry film button electronic devices circuit boards. Does tape have formaldehyde? What are the components of the tape?

Formaldehyde may be present in the tape

Formaldehyde is a relatively highly toxic chemical substance. It ranks second in the list of priority control for toxic chemicals in China. Formaldehyde has long been designated as a carcinogen and teratogenic chemical substance by the WHO. It is a well-known source of hypersensitivity reaction and one of the hidden strong mutants.

The tape component usually includes the base material, the sheet spring and the adhesive substrate is the main part of the tape such as paper cloth and plastic film; the sheet spring is the component used in the tape to increase strength and stiffness; the adhesive is the component that allows the tape to be adhered to the object.

What material is better for tape

PVC (polyethylene) tape: PVC is a common tape material with good wear resistance, waterproof performance and heat resistance. It is suitable for insulating layer packaging and binding in electronic devices, household appliances and vehicles and other fields.

Paper tape: Paper tape is generally based on paper, has good adhesion and compressive strength, and is suitable for printing paper paste and binding.

Cloth-based tape: Cloth-based tape is based on fabric and has good tensile strength and adhesion. It is suitable for the bonding and binding of various wood, metal materials, laminated glass and other materials.

Silicone rubber tape: Silicone rubber tape has good heat resistance, reduction resistance and corrosion resistance, and is suitable for insulating layer sealing, thermal insulation and insulation in electronic devices, household appliances and vehicles and other fields.

Polyurethane tape: Polyurethane tape has good wear resistance tensile strength and adhesiveness, suitable for bonding and binding of various materials
