2023-12-26

Sinrylion is a leading monofilament yarn manufacturer in China. At present, in modern industrial production, various elastomer materials are increasingly widely used, among which TPEE, PA, and TPEE+TPU monofilament are three common materials. They differ significantly in performance, use and production processes.


TPEE (thermoplastic polyester elastomer) monofilament


TPEE is a thermoplastic elastomer made from a blend of polyester fiber and polyether fiber. It combines the elasticity of rubber with the processability of plastic, so it is widely used in many fields.


Features


1.TPEE has good high temperature resistance and chemical corrosion resistance.


2. Able to maintain good performance in the temperature range of -50℃ to +200℃.


3. TPEE also has excellent fatigue resistance and creep resistance, and can maintain stable performance under repeated stress.


Production Process


1. Raw material selection: The synthesis of TPEE requires the use of a variety of raw materials, including melamine, acrylic acid, accelerators, etc. The selection and quality of these raw materials have an important impact on the performance and stability of TPEE. Therefore, the quality and purity of raw materials need to be strictly controlled during the production process.


2. Reaction synthesis: The synthesis of TPEE is usually carried out by polymerization reaction. In the reaction, melamine and acrylic acid form TPEE through free radical polymerization. In order to control the reaction process, factors such as reaction temperature, reaction time, and reactant ratio need to be accurately controlled.


3. Post-processing: The production process of TPEE usually also includes post-processing steps, such as filtration, drying, cutting, etc. These steps can further improve the physical properties and processing properties of TPEE.


4. Process control: In order to ensure the stable quality and performance of TPEE, strict process control is required during the production process. This includes controlling reaction temperature, reaction time, reactant ratio, post-treatment steps and other aspects. At the same time, regular inspection and maintenance of production equipment and processes are also required to ensure their normal operation and stability.


Application


1.Automotive industry: TPEE monofilament can be used to manufacture automotive seals and rubber parts, such as sealing rings, fenders, etc. These parts need to have good wear resistance, high temperature resistance and chemical corrosion resistance, and TPEE materials can meet these requirements.


2.Electronic and electrical appliances: In the electronic and electrical appliance industry, TPEE monofilament can be used to manufacture mobile phone cases, computer cases, etc.


3.Sports and cultural products: Due to its good elasticity and mechanical properties, TPEE monofilament is also used in sports equipment, sports shoes and other cultural and sports products.


4.Biomaterials: TPEE monofilaments have good biocompatibility and stability, so they are also used in the field of biomaterials, such as making medical equipment and implants.


5.Other fields: In addition to the above fields, TPEE monofilaments are also used in other fields such as chemical industry, petroleum, and textile.


PA (nylon) monofilament


An engineering plastic consisting of polymers bonded by amide bonds.


Features


1.Has good mechanical properties, heat resistance and wear resistance.


2.PA has high strength, good toughness and can withstand large stress.


3.PA also has good chemical corrosion resistance and oil resistance, and can maintain good performance in a variety of harsh environments.


4.The disadvantage of PA is that it is highly hygroscopic and easily affected by moisture, which affects its mechanical properties. In addition, PA has relatively poor high temperature resistance and can only be used at temperatures ≤100°C.


Production Process


1.Raw material preparation: According to production needs, select appropriate raw materials, such as adipic acid, hexamethylenediamine, etc., and perform measurement and pretreatment.


2.Polymerization reaction: Add the raw materials into the polymerization reactor, and perform the polymerization reaction under a certain temperature, pressure and catalyst to generate nylon polymer.


3.Granulation: The nylon polymer generated by the polymerization reaction is pelletized to make granular products.


4.Drying: Dry the cut granular products to remove moisture and volatile substances.


5.Processing and molding: The dried nylon particles can be made into products of various shapes through injection molding, extrusion, blow molding and other processing techniques.


6.Quality inspection: Conduct quality inspection on processed and formed nylon products, including inspection of appearance, size, performance, etc.


Application


1.Fishing line: PA monofilament has high strength and wear resistance, so it is widely used in fishing line. It can withstand large pulling forces and is not easy to break, ensuring the safety of anglers.


2.Industrial manufacturing: In the field of industrial manufacturing, PA monofilament is used to manufacture various nets, filters, brushes, etc. Due to its excellent high temperature resistance and chemical corrosion resistance, PA monofilament has high practical value in industrial production.


3.Medical field: In the medical field, PA monofilament is used to manufacture surgical sutures, dental floss and other medical equipment. Due to its excellent biocompatibility and stability, PA monofilament has broad application prospects in the medical field.


4.Packaging materials: Because PA monofilament has good gas barrier properties and oil resistance, it is used in food packaging materials. It can effectively protect food from environmental factors such as oxygen and humidity, and extend the shelf life of food.


5.Electronics industry: In the electronics industry, PA monofilament is used to manufacture wire insulation layers, cable shielding layers, etc. It has excellent electrical insulation properties and high temperature resistance, which can ensure the safety and reliability of electronic products.


TPEE+TPU monofilament


TPEE+TPU monofilament is a new type of composite material made of a blend of TPEE and TPU (thermoplastic polyurethane).


Features


This material combines the advantages of TPEE and TPU. It has the elasticity and high temperature resistance of TPEE and the wear resistance and oil resistance of TPU. Compared with using TPEE or TPU alone, TPEE+TPU monofilament has better overall performance. In addition, the production process of TPEE+TPU monofilament is simple and the cost is low.


Production Process


1.Ingredients: According to production needs, measure and mix TPEE and TPU raw materials to form a uniform mixture.


2.Melt extrusion: Add the mixture into the melt extruder and perform melt extrusion under high temperature and high pressure to form continuous TPEE+TPU monofilament.


3.Cooling and solidification: The extruded monofilament is cooled and solidified to give it a certain shape and stability.


4.Winding: Winding the cooled monofilament to facilitate subsequent processing and use.
