一.Product introduction
SEBS is a linear terromer with
polystyrene as the terminal segment and ethylene-butene copolymer with polybutadiene
hydrogenation as the intermediate elastic block. SEBS contains no unsaturated
and double bonds, so it has good stability and aging resistance.
二.
Purpose
of SEBS:
1.SEBS
has good uv stability, oxygen resistance and thermal stability, so it can also
be used in roofing and road repairing asphalt.
2.SEBS
is miscible with paraffin, so it can be used for flexible surface coating of
paper products.
3.SEBS
is temperature-insensitive without obvious shear flow during heating, so it can
be used as a template for IPN. (basic principle of IPN: two insoluble polymers
can achieve mutual penetration of the entangled chain segments. For example,
two insoluble polymers can be "locked" together by cross-linking
through covalent bonds.)
4.
The organic solution of SEBS oil blend can substitute for natural rubber latex
to manufacture surgical gloves and other products.SEBS has the following two
advantages due to its lack of unsaturated double bond and high purity :(1) good
oxygen resistance and ozone resistance; (2) while natural rubber contains
proteins that can cause dangerous allergic reactions in some patients, this
blend does not.
三、Specific performance of SEBS:
With excellent aging resistance,
SEBS has both plasticity and high elasticity. It can be processed and used
without vulcanization. The leftover material can be used heavily. SEBS has good
weather resistance, heat resistance, compression deformation resistance and
excellent mechanical properties:
(1)Better temperature resistance, its embrittlement temperature ≤-60℃, the highest use temperature up
to 149℃, in the oxygen atmosphere its decomposition temperature is more than
270℃.
(2)excellent aging resistance,
aging in the artificial accelerated aging box for a week its performance
decline rate is less than 10%, ozone aging (38℃) for 100 hours its performance
decline is less than 10%.
(3)excellent electrical properties,
its permittivity at 1 KHZ is 1.3*10-4, 1 MHZ is 2.3*10-4; Volume resistivity is
a minute 9 * 1016 Ω/cm; 2 minutes to 2 * 1017 Ω/cm.
(4)good solubility, blending performance and excellent oil charging, can
dissolve in many common solvents, its solubility parameters between 7.2~9.6,
can be mixed with a variety of polymers, can be used in the rubber industry
commonly used oils, such as white oil or naphthene oil.
(5)without vulcanization can be
used elastomer, processing performance is similar to SBS, waste material can be
used again, in line with environmental requirements, non-toxic, in line with
FDA requirements.
(6)lighter than others, about 0.91,
the same weight can produce more volume of the product.
四、 Processing method
SEBS blends can be made by
thermoplastic processing methods such as injection, extrusion and blow molding.
SEBS and SBS differ in product structure and processing temperature. In terms
of processing temperature, SBS processing temperature is generally between 150
and 200℃, and SEBS is generally between 190 and 260℃. In SBS processing, the shear
rate is required to be low, while in SEBS processing, the shear rate is
required to be high. Injection molding, SBS generally use moderate shear rate,
extrusion molding generally use low compression ratio of screw, and SEBS processing,
should use high injection rate and high compression ratio of screw.
1、YH-501
The production of heat melt
pressure-sensitive adhesive initial adhesion, peeling force moderate, good
cohesion, can be used for the production of packaging protective film; Adding
appropriate amount of SIS in YH-501 can effectively improve the initial
adhesion and peeling strength of hot-melt pressure-sensitive adhesive, and can
prepare high performance pressure-sensitive adhesive. The hot melt adhesive
produced by YH-501 has the characteristics of good flow performance, good creep
resistance, aging resistance and high cohesion strength, and can be used for
the production of high-grade carpet and non-slip floor mat back glue. It can
also produce hot melt adhesive for wood, paper, fiber, leather, metal, plastic,
etc.

4、YH-503
Thermoplastic rubber YH-503
molecular weight is the highest in linear SEBS, with excellent mechanical
properties under high filling and complete double INP network formed when
mixing with PP, which is mainly used for blending products.
YH-503 is mainly used for the
basic materials of blend elastomer, such as various coating materials, sealing
strips, anti-vibration materials, road sign paint, other elastomer
reinforcement, plastic toughening and modification, etc.
YH-503 can be blended with most
plastics during processing, and different plastics have different influences on
the properties of the final products. For example, when powdery PPO is added
into YH-503 blend materials, the phase separation between styrene and butadiene
is strengthened, and the temperature resistance, mechanical properties,
rigidity and smooth surface of elastomer are significantly enhanced. When
adding an appropriate amount of alpha-methyl styrene and acrylonitrile to the
copolymer, the surface of the product is non-stick, so YH-503 should be used
according to the application characteristics of the final product, strengthen
its required performance.
