Product Characteristics of Low Density PVC Foam Tape
- Light weight and high strength: Low-density PVC foam tape achieves a good balance between weight and performance with its low density (usually between 110kg/m³ and 500kg/m³, depending on the product model) and high strength.
- Excellent sealing properties: the tape, when compressed (e.g. 30% compression) is able to effectively seal out substances such as water, dust, light, etc., making it suitable for scenarios where high sealing performance is required.
- Good vibration damping and soundproofing properties: the low density PVC foam tape has good vibration damping and soundproofing effects, which can reduce noise and vibration and enhance the comfort of use.
- Weathering and UV resistance: The material has excellent weathering and UV resistance properties, and is able to maintain stable performance in a variety of environmental conditions.
- Good insulating properties: The low-density polyvinyl chloride foam tape also has excellent insulating properties, which can be used for the insulation treatment of electrical equipment to prevent leakage and short circuit.
- Flame retardant: Some products can be customised according to the requirements of flame retardant grade, such as reaching UL-94-V-0 grade or BS476:part7:1997 Class Ⅰ and other standards, to improve the safety of use.
- Easy processing: Foam tape can be cut, pasted and other processing according to the needs of use, easy to use. Based on these qualities, it’s easy to see its areas of application
Application Areas of Low Density PVC Foam Tape
- Home decoration: Paste wallpaper, decorative paintings and other wall decorations, provide solid adhesion and will not cause damage to the wall. Fixing furniture feet, door handles and other small objects, play a shock absorption and fixed role. Fixing and damping home appliances, such as TV sets, refrigerators, etc., to reduce noise and vibration.
- Industrial Manufacturing: Fixing and protecting wires, cables, pipes and other parts to ensure stability and safety in the working process. Insulation treatment of electrical equipment to prevent leakage and short circuit. Filling materials and anti-vibration materials in the packaging industry to protect products from damage during transport.
- Electronic appliances: Encapsulation and fixation of mobile phone panels, protection of LED displays, insulation protection of inductor winding, etc.
- Mechanical Manufacturing: Fixing of motor stator coil winding, wrapping protection of transformer core, etc.
- Other fields: Photographic field for fixing and adjusting photographic equipment. In the medical field, it is used for fixing medical equipment and patients’ body parts. Aerospace, automotive manufacturing and other fields due to its unique performance and get applications.
Production Process of Low Density PVC Foam Tape
Because you may start to wonder after reading about its physical properties how it has managed to be used in so many fields, here’s how it’s produced. If you are not interested you can skip to the next part.
The production process of low-density polyvinyl chloride foam tape includes the following steps:
- Raw material preparation: the main raw material is polyvinyl chloride resin, adding plasticisers, stabilisers and other auxiliary materials.
- Foaming: Through calendering or extrusion moulding process, the raw material foams to produce uniform independent bubbles, forming foam material.
- Coating of adhesive: The foam material is evenly coated with a layer of adhesive to form an adhesive layer through the coating machine or coating process.
- Drying and curing: After coating the adhesive, the foam material enters the oven or drying room for drying and curing to ensure that the adhesive is fully cured.
- Cutting and packaging: The dried and cured foam material is cut into standard-sized tape rolls according to demand, and is rolled and packaged ready for sale.
Market Status of Low Density PVC Foam Tape
In recent years, with the progress of science and technology and the improvement of people’s living standards, the application fields of low-density polyvinyl chloride foam adhesive tape have been expanding. Especially in electronic and electrical appliances, machinery manufacturing, packaging and transport industries, its demand continues to grow. At the same time, with the enhancement of environmental protection awareness, the market demand for biodegradable, environmentally friendly foam tape is also increasing.
Nowadays, low density polyvinyl chloride (PVC) foam tape is mainly produced in China. And China also has significant production advantages, mainly reflected in the following aspects:
As one of the world’s largest producers and consumers of plastics, China has a well-developed plastics industry chain and strong production capacity, which provides a solid industrial foundation for the production of lightweight and high-strength low-density polyvinyl chloride (PVC) foam tape.
- China’s technological level in the field of polymer materials has been continuously upgraded, including the preparation and processing technology of foam. This makes the low-density polyvinyl chloride foam tape produced in China reach the international advanced level in sealing performance.
- The abundant supply and relatively stable price of polyvinyl chloride (PVC) raw materials in China provide a strong guarantee for the production of low-density PVC foam tapes with excellent weather resistance and UV resistance.
- The Chinese government attaches great importance to the development of the new materials industry and has introduced a series of policies and measures to support technological innovation and industrial upgrading in the field of polymer materials. This provides a favourable policy environment for the production of low-density polyvinyl chloride foam tape with excellent insulating properties.
- Chinese enterprises have strict standards and systems for quality control to ensure that the low-density polyvinyl chloride foam tape produced meets international standards in terms of flame retardancy and other aspects to guarantee the safety and reliability of the product.
- The Chinese market offers a wide range of low-density polyvinyl chloride foam tapes with complete specifications, which can meet the needs of different industries and fields. Consumers can choose the right products according to their needs, and these products are easy to process and customise.
So if you want PVC TAPE, you can also consider inexpensive Chinese companies that are known for their product quality, price advantage and market reputation, such as Shanghai Toptape, Yingtai Plastic and Alibaba International.
In summary, low-density polyvinyl chloride foam tape occupies an important position in the market with its unique performance and wide range of applications. In the future, with the continuous progress of technology and the continuous expansion of the market, its development prospect will be more broad.
