Difference between TPU industrial caster and Pu universal caster
Caster TPU (thermoplastic polyurethane elastomer) is a new plastic
variety. Because caster TPU has
good processability, weather resistance and environmental
protection, it is widely used in shoe
materials, pipes, films, rollers, cables and wires and other
related industries. Polyurethane thermoplastic
elastomer, also known as thermoplastic polyurethane rubber,
referred to as caster TPU for short, is a
(AB) n-type block linear polymer. A is polyester or polyether with
high molecular weight (1000-6000),
B is diol containing 2-12 linear carbon atoms, and the chemical
structure between ab segments is
diisocyanate, usually MDI. Thermoplastic polyurethane rubber is
crosslinked by intermolecular hydrogen
bond or slight crosslinking between macromolecular chains. The two
crosslinking structures are reversible
with the increase or decrease of temperature. In the molten state
or solution state, the intermolecular
force decreases, and after cooling or solvent volatilization, there
is a strong intermolecular force
connected together to restore the properties of the original solid.
Polyurethane thermoplastic elastomers include polyester type and
polyether type. They are white
irregular spherical or cylindrical particles with a relative
density of 1.10-1.25. The relative density of
polyether type is smaller than that of polyester type. The glass
transition temperature of polyether type
is 100.6-106.1 ℃, and that of polyester type is 108.9-122.8 ℃. The
brittleness temperature of polyether
type and polyester type is lower than - 62 ℃, and the low
temperature resistance of hard ether type is
worried about that of polyester type.
Polyurethane thermoplastic elastomer is characterized by excellent
wear resistance, excellent ozone
resistance, high hardness, high strength, good elasticity, low
temperature resistance, good oil resistance,
chemical resistance and environmental resistance. In humid
environment, the hydrolysis stability of
polyether ester is much higher than that of polyester ester.
Polyurethane thermoplastic elastomer is non-toxic and tasteless. It
can be dissolved in solvents such as
methyl ethyl, cyclohexanone, tetrahydrofuran, dioxane and
dimethylformamide. It can also be dissolved in
the mixed solvent composed of toluene, ethyl acetate, butanone and
acetone in an appropriate proportion.
It is colorless and transparent and has good storage stability. PU
polyurethane is the general name of
polymer compounds formed by the reaction of diisocyanate or
polyisocyanate with compounds with more
than 2 hydroxyl groups. Its main chain contains many repeated NH
coo groups. Commonly used
diisocyanates include toluene diisocyanate (TDI), diphenylmethane
diisocyanate (MDI), hexane
diisocyanate (hd), isophorone diisocyanate (IP DI),
dicyclohexylmethane diisocyanate (HMD I),
polymethylene polyphenyl polyisocyanate (Papi), phenylenemethylene
diisocyanate (XDI), etc.
According to the different hydroxyl components used, it can be
divided into polyester type and
polyether type. It can be used for manufacturing plastic products,
wear-resistant synthetic rubber
products,syntheticfibers, hard and soft foam products, adhesives
and coatings. Casters TPU and
Pu casters are essentiallycomposed of the same material. But when
making these two compounds.
They use different formulations. These two compounds are divided
into many kinds of properties.
The characteristics of the compound made with different formulas
are not the same. These
characteristicsrefer to mechanical and physical characteristics.
