Used for plastic injection products, food packaging materials,
medical equipment, drugs, hollow blow molding products, fiber,
etc.
LLDPE product non-toxic, tasteless, odourless, white particles.
Compared with LDPE with high strength, good toughness, strong
rigidity, heat resistance, cold-resistant etc, and also has a good
environmental stress cracking resistance, resistance to tear
strength and other properties, and acid, alkali, organic solvents,
etc.Low density polyethylene (LDPE) is a kind of plastic material,
it is suitable for thermoplastic processing a variety of molding
process, molding, good workability. LDPE main purpose is for thin
film product, also used in plastic injection products, medical
devices, pharmaceutical and food packaging materials, hollow blow
molding products, etc.Pure polyethylene excluding polarity gene, so
has good dielectric properties. Molecular weight on the dielectric
properties of polyethylene doesn\'t happen, but if in the
polyethylene contains impurities, such as catalysts, metal exist in
the ash and molecular polar groups (such as hydroxyl and carbonyl
group), with its dielectric properties such as dielectric constant
and dielectric loss.LLDPE and HDPE is belong to the same linear
polyethylene, but LLDPE is ethylene and alpha olefin
copolymerization. Because of the LLDPE more than the high density
of copolymerization monomer copolymer, thus linear main chain of
LLDPE, there are a lot of short branched chain, leading to the
degree of crystallinity and low density polyethylene.In melt
stretch, LLDPE under various strain rate usually has lower
viscosity. This means it will not be like LDPE in generated when
the tensile strain hardening. With increasing the deformation rate
of polyethylene. LDPE shows a staggering increase of viscosity,
this is a low density polyethylene molecular chain.According to the
type of polymerization monomer, LLDPE is mainly divided into three
kinds of copolymer: C4 (butylene - 1), C6 (hexene - 1), and C8
(octene - 1). Among them, is the world\'s largest LLDPE resin
production, butene copolymer and hexylene copolymer is currently
the fastest growing varieties of LLDPE. In LLDPE resin, typical of
copolymerization monomer dosage is 5% ~ *0% weight fraction,
average usage is about 7%. Metallocene based LLDPE plastic body
(mLLDPE) with traditional LLDPE 3 times more than average comonomer
content.
General single lip wind ring stable enough to use on LDPE. LLDPE
characteristic of membrane bubble demand more perfect lips wind
ring to stability. Using internal film cooling on the lips, the
wind bubble can increase membrane bubble stability, at the same
time improve the film production capacity under high productivity.
In addition to membrane bubble better cooling, a lot of film
factory and LDPE blend method used to enhance LLDPE to dissolve the
word, the LLDPE extrusion can be done on the existing LDPE film
equipment, when the concentration of the blend of LDPE LLDPE was
*0%. Processing **0% LLDPE or rich in LLDPE and LDPE blend
material, using general of LDPE extrusion molding machine,
equipment necessary improvement
