Thermoplastic elastomer (TPE)

TPE (thermoplastic elastomer)

Thermoplastic elastomer (TPE)
 
First, Thermoplastic Elastomer (Thermoplastic Elastomer) is a material that combines the properties of thermoplastics and traditional vulcanizates. It is the so-called third-generation rubber following natural rubber and synthetic rubber, abbreviated as TPE or TPR (Thermoplastic Rubber). Commercial varieties of the TPE family include TPEE, TPAE, TPU, TPR, TPV, POE, and SBC. Features are as follows:
 
1, no vulcanization
 
2, easy to mix
 
3, physical properties between vulcanized rubber and plastic
 
4, materials can be recycled
 
The thermoplastic elastomer eliminates the traditional rubber vulcanization process during processing, and can be formed by injection, extrusion, blow molding, molding, etc., in the same way as plastics. The molding rate is faster than that of conventional vulcanized rubber, and the molding material can be reused. .
 
Second, TPE (TPEE, TPAE, TPU, TPR, TPV, POE, SBC) family can provide the following feature level products:
 
1, transparent series: the appearance of transparent, smooth surface, soft touch, non-toxic, anti-slip, hardness adjustable;
 
2, weather series: excellent weather resistance, heat resistance, wear resistance;
 
3, food grade: FDA, NSF meet;
 
4, coating level (secondary injection bonding): can be a variety of (PP, PS, PC, ABS, PA, EVA) materials, secondary injection bonding, in order to increase its comfort, safety, wear resistance, Aesthetics, slip resistance;
 
5, extrusion grade: Excellent electrical insulation, excellent flexibility, flexibility
 
Third, application:
 
1, transparent series: toys, soft insoles, insoles, toe sheath, ball pen grip ring, bait, sex toys, shoe roots, ice box;
 
2, weather series: automotive seals, outdoor use parts;
 
3, food grade: ice box, various food containers;
 
4, coating level: a variety of grips, shell coating, toothbrush handle coating, cap gaskets, stationery;
 
5, extrusion series: chest expansion, automotive carpet, wire and cable, computer cable.
 
In summary, TPE family materials can be used in the following areas:
 
Children's toys, massage equipment, sporting goods, luggage accessories, cutlery products, tool handles
 
Daily necessities, auto parts, industrial casters, plastic modification, sealing strips, anti-slip mats

Single material description
 
1, TPV
 
1. TPV (EPDM/PP type thermoplastic dynamic vulcanizate) uses EPDM as the rubber phase, PP as the continuous phase, and a stable elastomer obtained after dynamic vulcanization.
 
Dynamic vulcanization means that the rubber is vulcanized during the melt-mixing of the rubber phase and the non-vulcanizable thermoplastic polymer to obtain a granular vulcanized rubber phase, and the morphology of the rubber micro zone is very stable, and no materialization changes occur during processing.
 
Second, TPV performance characteristics:
 
TPV successfully combines some properties of vulcanized rubber, such as heat resistance and low compressive deformation with the ease of processing of thermoplastics. Excellent anti-dynamic fatigue resistance, high tear resistance, excellent weatherability, good abrasion resistance, excellent corrosion resistance to water-based acid-base liquids, polar oils, at -40°C It is possible to use in the range of ~ +150°C.
 
EPDM/PP type thermoplastic dynamic vulcanizates (TPV) have the environmental resistance equivalent to the universal EPDM rubber material, and their oil and solvent resistance are comparable to general-purpose neoprene rubber.
 
1, rubber feel, plastic processing methods.
 
2. Mechanical performance within the effective operating range of -40°C to +150°C.
 
3, for water-based liquids, oils and hydrocarbons with neoprene grade oil and solvent resistance.
 
4, compression deformation and permanent deformation is small.
 
5. Exposure at 150°C for two weeks or exposure at 125°C for a longer time reveals its excellent heat resistant air aging properties.
 
6, excellent anti-dynamic fatigue properties.
 
7, high tear strength.
 
8, excellent ozone resistance and weather resistance.
 
9, with polypropylene (PP) or nylon (PA) has excellent adhesion.
 
Third, TPV is mainly used in:
 
Automotive parts: Glass slide rails, glass edge seals, hood seals, hoses, hoods, dust covers, shock mounts, air ducts, etc.
Mechanical tools: Impact rods, casters, gaskets, handles, grips, hoses, rubber rollers, take over fittings, etc.
Buildings and structures: glass seals, door seals, arch bases, pipe washers, sanitary fittings, building expansion joints, etc.
Electronic appliances: cable jacket, mobile phone antenna, motor shaft, bearing, splicing tape, button pad diaphragm, transformer shell and so on.
Sports equipment: ball skin, racket handle, rifle butt pad, underwater breathing apparatus, ski pole handle and so on.
 
2, TPEE
 
1. TPEE (thermoplastic polyester elastomer) is a block copolymer containing a polyester hard segment and a polyether soft segment;
 
1, TPEE:
 
A, rubber elasticity (TPEE has better processing performance and longer service life than rubber);
 
B. The strength of engineering plastics;
 
C. Polyether soft segment and uncrystallized polyester form an amorphous phase, and the hard segment of the polyester crystallizes to form a crystalline micro region, which acts as a physical cross-linking point; D, the soft segment gives it elasticity, making it like rubber;
 
E. The hard segment gives it processing properties, making it like a plastic (better strength, flexibility, dynamic mechanical properties than engineering plastics).
 
Second, TPEE performance and characteristics:
 
1, with high strength, high elasticity, oil resistance, acid and alkali resistant, high temperature, radiation resistance, dynamic mechanical properties and other characteristics;
 
2, the use of temperature range: -50 °C ~ +180 °C,
 
3, hardness range of 30-75D, divided into high-performance grade, extrusion grade, blow molding grade, flame retardant grade and modified grade:
 
High-performance grade: high structural strength, good creep resistance, excellent resilience, impact resistance and bending fatigue, wear resistance, and dimensional stability. Flexibility at low temperatures, good performance at high temperatures, resistance to corrosion from many industrial chemicals, oils, and solvents.
 
Extrusion grade: In addition to the characteristics of high performance grade, the melt strength is better and it is specially used for extrusion molding.
 
Blow molding grade: In addition to its high performance grade, it also has good melt strength.
 
Modified grade: It is a multi-block copolymer and is an excellent plastic modifier for improving the impact resistance of POM and PBT.
 
Flame-retardant grade: It is a blend of high-performance grade and self-made flame-retardant masterbatch to meet the requirements of material flame retardant:
 
a, UL-94 V-0 level (Oxygen Index 27);
