Plate Flange/PL Flange hot sales

Plate flanges are commonly used in applications where the mating flange or flanged fitting is made from a casting. JSFITTINGS offers plate flanges according to ASME/ANSI B16.5 and GOST,EN1092 standards, in both carbon steel and stainless steel. What are Plate flanges? A Plate Flange is a type of flange that is made from a flat piece of metal, typically steel or stainless steel. The flange is cut and formed to shape, with a raised face on one side and a recessed area on the other side. It is often referred to as a flat flange, a plain flange, and flange slip, etc. Two plate flanges can be bolted together with a gasket in between them, usually used in fuel and water pipelines. Plate flanges have a serrated finish on the inner mating surface, allowing the plate to fit within the material of the gasket. In any given dimension, plate flange designs are standardized regardless of the materials used to manufacture them. What are the plate flange Advantages? Plate flanges have several advantages, such as: Easy to Manufacture: Plate flanges can be easily manufactured by cutting and shaping a flat plate. Cost-Effective: Plate flanges are relatively inexpensive compared to other types of flanges, making them a cost-effective option. Customizable: Plate flanges can be customized to suit specific application needs, such as different pressure ratings and sizes. ASME ANSI B16.5 Plate Flange Plate flanges Application: Plate flanges have several uses, such as: Piping Systems: Plate flanges are commonly used in piping systems to connect pipes and other fittings. Industrial Applications: Plate flanges are used in various industrial applications, such as oil and gas, chemical, and power plants.

OPE wax for pvc products

Oxidized polyethylene wax serves as a highly important and efficient external lubricant and processing aid in PVC manufacturing. It plays an irreplaceable role by enhancing processing fluidity and improving the surface quality of finished products. 1. Superior External Lubrication Effect Mechanism: The molecular chains of oxidized polyethylene wax carry polar groups such as carboxyl and hydroxyl groups. These groups enable one end to weakly anchor onto PVC molecular chains, while the long-chain alkane groups at the other end extend outward. Effect: This creates an effective lubricating film between the PVC melt and the metal surfaces of processing equipment (e.g., barrels, screws, molds). This film significantly reduces friction between the melt and metal surfaces, preventing melt adhesion to equipment. Consequently, material is easier to convey, plasticize, and demold. 2. Promoting Plasticization and Improving Flowability Although primarily functioning as an external lubricant, its moderate polarity provides slight compatibility with PVC, preventing complete “slippage” unlike paraffin wax. It reduces friction-induced heat while ensuring effective shear force transfer, aiding uniform plasticization of PVC resin. This lowers melt viscosity and enhances flowability.

OPE wax for film processing

Oxidized polyethylene wax plays multiple critical roles in film processing. The carbonyl and hydroxyl groups on its molecular chain confer exceptional polarity, enabling it to form strong complex bonds with polar resins such as PVC, thereby significantly enhancing lubrication performance. Functioning as both an internal and external lubricant, it reduces friction between materials and equipment to prevent roller adhesion while also diminishing intermolecular friction, improving plasticisation efficiency and balancing internal and external lubricity. Its low viscosity and high dispersibility further promote uniform filler distribution, resulting in smoother, flatter film surfaces with enhanced gloss and transparency. Concurrently, OPE wax's high softening point and hardness strengthen the film's heat resistance and structural integrity, preventing deformation at elevated temperatures. Moreover, its non-toxicity and thermal stability facilitate widespread application in sectors like food packaging, while its environmental credentials align with industry trends. Overall, OPE wax effectively enhances film processing efficiency and product quality through mechanisms including lubrication, dispersion, and compatibility.

OPE wax for plastic and rubber

Oxidized polyethylene wax is an excellent new type of polar wax. Due to the presence of a certain amount of carbonyl and hydroxyl groups in its molecular chain, it exhibits significantly improved compatibility with fillers, pigments, and polar resins. It serves as a dispersant, lubricant, brightener, and coupling agent for pigments or fillers in applications such as concentrated color masterbatches, polypropylene masterbatches, additive masterbatches, and filler masterbatches. As a lubricant, release agent, and compatibilizer in rubber and plastic processing, EVA wax exhibits excellent compatibility with various rubbers. Its high melting point and low viscosity enhance resin flowability, relatively reduce energy consumption during resin mixing, minimize adhesion between resin and molds, facilitate easy demolding, and provide both internal and external lubrication. It also offers good antistatic properties. As a dispersant and anti-scratch agent in inks. As a viscosity regulator in hot melt adhesives.

Fischer tropsch wax candle making

Ft wax is an excellent, high-end candle-making material, particularly suitable for producing high-quality container candles, pillar candles, and decorative candles. High melting point: The melting point range is very broad (typically between 90-110°C), making it ideal for candles requiring high heat resistance. Hard texture: The candles produced are very hard, resistant to scratches and deformation, with a smooth surface. Low/no oil content: It contains almost no oil, meaning it burns smoke-free, odourless, and clean. Excellent shrinkage: It has a high shrinkage rate when cooling, making it very easy to remove from moulds. White/transparent: It is naturally white in colour, making it an excellent base for colouring, capable of producing vibrant hues.

Micronized wax for spinning and weaving

Micronized wax is primarily applied to textiles in the finishing process by blending it with other finishing agents (such as resins, adhesives, etc.) and applying it to the fabric through methods like padding, coating, or printing. Its main functions include: Improving and Adjusting Hand Feel: Smoothness: This is the core function of Micronized wax. The wax powder forms an extremely thin, uneven film on the fiber surface, effectively reducing the friction coefficient between fibers, thereby imparting excellent smoothness, softness, and a fluffy hand feel to the fabric. Softness: It compensates for the stiffness that some resin finishes may cause, making the fabric more comfortable to the touch. Anti-Blocking Properties: For coated fabrics, films, or synthetic fabrics (especially nylon and polyester), which are prone to sticking together under heat or pressure, Micronized wax creates micro-protrusions on the surface, reducing the actual contact area between materials. This effectively prevents adhesion, facilitating subsequent cutting and sewing processes. Abrasion and Scratch Resistance: The wax particles act like "ball bearings" on the fiber surface, allowing external friction objects to glide over more easily rather than directly scraping the fibers. This protects the fibers and coatings, enhancing the fabric's durability. Matting Effect: Micronized wax causes diffuse reflection of light, disrupting specular reflection, thereby reducing the fabric's gloss to some extent and creating a soft, elegant matte effect. This is related to its particle size and dosage.
