TPE
(Thermoplastic Elastomer) is a rubber having a high elasticity, high strength,
high elasticity, but also has the characteristics of injection molding of the
material. Eco-friendly
non-toxic safe, wide range of hardness, excellent coloring, soft touch, weather
resistance, fatigue resistance and temperature resistance, excellent processing
performance, not curing, can be recycled to reduce costs, both the second
injection molding, and PP,
PE, PC, PS, ABS and other adhesive coated substrate can also be formed
separately.
Thermoplastic elastomers
with both thermoplastic processing performance, but also has the physical
properties of vulcanized rubber, plastic and rubber can be described as a
combination of advantages advantages. Thermoplastic elastomers are wantonly originally
occupied territory belongs only vulcanized rubber.
TPE
(Tetraphenylene) is a classic AIE (Aggregation Induced Emission AIE) molecules,
ie no fluorescence in solution, but the solid but there is a strong fluorescence
quencher molecule with the traditional gathering just the opposite, so the
organic photoelectric materials and
other areas has important applications, but also more and more cause for
concern.
TPE advantages:
1 generally available thermoplastic
molding machine, does not require special processing equipment.
(2) a substantial increase in production efficiency. Can
be directly vulcanized rubber injection molding machine, the time from about
20min, shortened to less than 1min; need curing time is very short, it is
already available direct vulcanization extruder production efficiency greatly
improved.
3 easy to recycle and reduce
costs. Waste
generated in the production process (escape flash, out of waste plastic) and the
final waste can be returned directly reused; used TPE old products can be simple
regeneration recycling, reduce environmental pollution, expanding sources of
renewable resources.
4 Conservation. Most thermoplastic elastomers do not
require curing or curing time is very short, can effectively save energy. Energy
consumption in high-pressure hose example: rubber 188MJ/kg, TPE is 144MJ/kg, can
save energy up to 25% or more.
5 wider field
of applications. TPE combines
the advantages of rubber and plastic, rubber industry has opened up new fields
of application.
6 can be used for
plastic reinforced, toughened. Since the reinforcement, the formula
simplifies, with the impact of constraints on the polymer dose is small, the
quality of performance easier to grasp. TPE heat resistance than rubber,
as the temperature rises and properties decreased greatly, and thus the scope is
limited. Meanwhile,
deformation, elastic recovery and durability equivalent to less than rubber, the
price is often higher than the same rubber. Nevertheless, TPE advantage is still
very prominent, a variety of new TPE products are constantly developed. As an energy saving rubber new
materials, the development is very promising.
