PVC coated fabric and PVC extruded fabric are two common industrial fabrics that are coated with a layer of polyvinyl chloride (PVC) plastic film on the surface of the fabric. They have characteristics such as waterproofing, fire prevention, mold resistance, cold resistance, corrosion resistance, aging resistance, and high temperature resistance, and are widely used in automotive, new materials, advertising materials, outdoor, engineering, and other fields. However, there are also some obvious differences between them, mainly reflected in production methods, ingredients, performance, and durability. This article will compare and analyze them from these aspects, hoping to be helpful to you.

Production method

The different production methods of PVC coated fabric and PVC extruded fabric result in differences in their surface morphology and thickness. PVC coated fabric is a plastic film with special properties that is coated with a layer of PVC paste on the surface of the fabric, and then processed through foaming, curing, and other processes. The thickness of PVC paste can be adjusted as needed, usually between 0.1-0.5 millimeters. The surface of PVC coated fabric is smooth and flat, with bright colors and diverse patterns. It can produce different functional fabrics according to different needs, such as waterproof cloth, fireproof cloth, mold resistant cloth, UV resistant cloth, etc. PVC extruded fabric is a layer of PVC film pressed onto the back of the fabric, and then subjected to high-temperature pressing, drying, and other processes to form a thick plastic film. The thickness of PVC film is generally between 0.3 and 1.0 millimeters, which is much thicker than PVC coated cloth. The surface of PVC extruded fabric has obvious textures, darker colors, and fewer patterns, mainly used for making pull rod bags, construction tents, waterproof covers, etc.

component

The composition of PVC coated fabric and PVC extruded fabric is also different, resulting in differences in their physical and chemical properties. The composition of PVC coated cloth mainly depends on the composition and formula of PVC paste. Different auxiliary materials such as plasticizer, anti-aging agent and mildew inhibitor will affect its heat resistance, toughness and ductility. Generally speaking, the PVC content of PVC coating cloth is between 30-50%, the plasticizer content is between 10-30%, and the content of other auxiliary materials is between 10-20%. The composition of PVC extruded fabric mainly depends on the composition and quality of the PVC film. Generally speaking, the PVC content of PVC extruded fabric is between 60-80%, the plasticizer content is between 10-20%, and the content of other auxiliary materials is below 10%. Due to the high PVC content and low plasticizer content of PVC extruded fabric, its hardness, stiffness, strength, etc. are higher than those of PVC coated fabric. However, its softness, toughness, ductility, etc. are lower than those of PVC coated fabric.

performance

The performance of PVC coated fabric and PVC extruded fabric is also different, leading to differences in their scope of application and usage. The performance of PVC coated fabric mainly depends on the formula and process of PVC paste, and its waterproofing, fire resistance, mold resistance, UV resistance, etc. can be adjusted according to different needs. Generally speaking, PVC coated cloth has good waterproof performance, can reach a water pressure of 2000-5000 millimeters, and is suitable for making raincoats, umbrellas, tents, etc. PVC coated fabric also has good fire resistance and can meet the B1 level flame retardant standard, making it suitable for making fire doors, fire curtains, etc. PVC coated fabric also has good anti mold performance, which can effectively prevent the fabric from getting moldy and deteriorating. It is suitable for making sofas, mattresses, etc. PVC coated fabric also has good UV resistance and can effectively prevent fabric fading and aging, making it suitable for making sunshades, sunshades, etc. The performance of PVC extruded fabric mainly depends on the thickness and quality of the PVC film. Generally speaking, PVC extruded fabric has strong waterproof performance, can reach a water pressure of 5000-10000 millimeters, and is suitable for making waterproof covers, waterproof boxes, etc. The fire resistance of PVC extruded fabric is also strong, and it can meet the flame retardant standards of B1 or B2, making it suitable for making fire-resistant fabrics, fire-resistant boards, etc. PVC extruded fabric also has strong cold resistance and can maintain its performance in low temperature environments below -30 ℃, making it suitable for making refrigerated bags, refrigerated boxes, etc. PVC extruded fabric also has strong corrosion resistance and can withstand the erosion of chemical substances such as acids, alkalis, and salts, making it suitable for making chemical bags, chemical boxes, etc.

durability

The durability of PVC coated fabric and PVC extruded fabric is also different, leading to differences in their service life and maintenance methods. The durability of PVC coated fabric mainly depends on the quality of PVC paste and the strength of the fabric. Generally speaking, the service life of PVC coated fabric is between 3-5 years. If used improperly or damaged by external forces, it may lead to the detachment, cracking, deformation, etc. of PVC paste. The maintenance method of PVC coated cloth is relatively simple, just wipe it with a damp cloth or clean it with a neutral detergent, do not use organic solvents or dry it at high temperature to avoid affecting its performance. The durability of PVC extruded fabric mainly depends on the quality and thickness of the PVC film. Generally speaking, the service life of PVC extruded fabric is between 5-10 years. If used improperly or damaged by external forces, it may lead to the rupture, perforation, fading, etc. of the PVC film. The maintenance method of PVC extruded fabric is relatively complex, requiring regular use of a soft brush or vacuum cleaner to remove surface dust or stains. Do not scratch or puncture with sharp objects, and do not expose it to sunlight or high temperatures for a long time to avoid affecting its performance.

summary

PVC coated fabric and PVC extruded fabric are two different types of industrial fabrics, both of which have their own advantages and disadvantages and are suitable for different occasions and applications. The advantages of PVC coated fabric are smooth and flat surface, bright colors, diverse patterns, strong functionality, good waterproof, fire resistant, mold resistant, and UV resistant properties. It is suitable for making raincoats, umbrellas, tents, fire doors, fire curtains, sofas, mattresses, sunshades, sunshades, etc. The disadvantages of PVC coated cloth are its thin thickness, low hardness, stiffness, strength, and other properties, poor durability, easy detachment, cracking, deformation, etc., short service life, and relatively simple maintenance methods. The advantages of PVC extruded fabric are its thick thickness, high hardness, stiffness, strength, and durability, as well as strong waterproof, fireproof, cold resistant, and anti-corrosion properties. It is suitable for making waterproof covers, waterproof water tanks, fireproof fabrics, fireproof boards, refrigerated bags, refrigerated boxes, chemical bags, chemical boxes, etc. The drawbacks of PVC extruded fabric are its textured surface, darker color, fewer patterns, weaker functionality, lower softness, toughness, ductility, and other properties, longer service life, and more complex maintenance methods.
