The purpose is to reduce the surface adhesion of PET film and achieve the release effect. This product has excellent comprehensive performance and plays a key role in many industries.I. Product CharacteristicsMechanical propertiesTensile strength: The longitudinal tensile strength is 150 - 300MPa, and the transverse tensile strength is 100 - 200MPa. It can withstand large tensile forces, ensuring that the product is not easily broken during processing and use.Elongation at break: It is 100% - 300%, with good flexibility. It can be stretched to a certain extent without breaking, which is suitable for application scenarios that require deformation processing.Tear strength: It reaches 20 - 50kN/m, with strong resistance to tear damage, enhancing product durability and reducing the risk of tearing during use.Optical propertiesLight transmittance: As high as 90% - 92% or more, the proportion of light transmission is high, which is suitable for applications with high requirements for transparency, such as the protection and display of optical products.Haze: It is within 1% - 3%, with a low degree of light scattering, ensuring a clear product surface and not affecting the visual effect of the covered item.Thermal propertiesMelting point: It is 250 - 260°C, with high thermal stability. It can maintain its performance in a high-temperature environment and is suitable for processes involving high-temperature processing.Thermal shrinkage rate: The longitudinal and transverse thermal shrinkage rates are both 1% - 5%. The size is stable at a certain temperature, ensuring the shape accuracy of the product when the temperature changes.Release propertiesRelease force: The range is from a few grams per square centimeter to dozens of grams per square centimeter. For example, the release force of release film for ordinary tapes is 5 - 10g/cm2, and the release force of release film for high-strength adhesives is 30 - 50g/cm2. It can be accurately selected according to the characteristics of the adhesive and the use requirements.Release force uniformity error: It is controlled within ±10%, ensuring a uniform distribution of release force on the film surface, making the release effect of each part of the product consistent and improving the quality stability of the product.Chemical propertiesAcid and alkali resistance: After soaking in a solution with a pH value of 2 - 12, there is basically no obvious change in appearance and performance. It has strong tolerance to acid and alkali environments and can be used in environments containing acids and alkalis.Solvent resistance: The swelling rate is less than 5%. It is resistant to common organic solvents. It can maintain its performance when in contact with organic solvents and does not undergo excessive swelling to affect use.II. Product AdvantagesSmooth and flat surface: The coated surface is smooth and uniform, avoiding defects such as wrinkles, twitches, particles, bubbles, and pinholes, providing a high-quality surface for the protected or laminated materials.Excellent physical properties: Small thickness tolerance, high dimensional accuracy; low thermal shrinkage rate, stable dimensions when the temperature changes; good plasticity, easy to process and form.Strong chemical stability: PET material has good chemical stability and can resist the erosion of a variety of chemical substances, ensuring the stable operation of the product in complex chemical environments.Antistatic and scratch-resistant: Some products are treated with antistatic and scratch-resistant properties, reducing the impact of static electricity on the product and reducing the risk of surface scratches, protecting the surface quality of the attached material.III. Application AreasPackaging industry: It is used in labels, tapes, self-adhesive waterproof rolls, etc., facilitating the lamination and separation of materials and improving packaging efficiency and quality.Printing and screen printing industry: As a carrier or isolation material for the printed matter, it ensures uniform transfer of ink and prevents adhesion during the printing process.Electronics industry: It is used in the production of flexible circuits, insulating products, circuit boards, etc., protecting electronic components, facilitating processing operations, and improving the production accuracy and reliability of electronic components.Optical and reflective materials field: For example, in the production of reflective films, its good optical properties ensure the reflective effect and play an important role in traffic facilities, safety signs, etc.Pharmaceutical and hygiene products industry: In products such as plaster paper, toilet paper, and medical tapes, it provides a safe and reliable isolation function and meets hygiene standards.Die-cutting and stamping processing industry: As a release material in the die-cutting process, it enables the die-cut products to be accurately formed and improves the die-cutting processing efficiency and product quality.Q1:Could I have prices of your products?A1:Welcome.
