Lionpol
Thermoplastic Elastomers (TPE) or Thermoplastic Olefins
(TPO)
Thermoplastic elastomers (TPE or TPO varieties) enable
producers and users to custom design natural rubber
alternatives with very specific performance properties.
Lionpol thermoplastic elastomers TPE compounds are
designed for use in injection molding or extrusion
systems and are available in a variety of base polymers
including polyolefins and styrene copolymers.
Lion
Polymers offers a complete line of thermoplastic
elastomers (TPE as well as TPO) from Shore A hardness of
3 to 95 to a Shore D hardness of 55. Lion Polymers
“Lionpol” TPE's are especially suited for outdoor use
where light and oxidative stability are required.
Chemical resistance of our compounds is better than that
of many competing alternatives. Other performance
enhancing additive packages can be incorporated into any
product as end use performance requirements dictate.
Typical injection molding applications
for Lionpol thermoplastic elastomers include soft-touch
surfaces for tools, tooth brushes, hair brushes, mouse
pads and myriad other hand-held items. They can also be
used in place of plasticized PVC film or sheet for
cladding of various assemblies. Lionpol thermoplastic
elastomers (TPE or TPO) are available in natural or
pre-colored form. Filled or reinforced versions of most
of our products are available by request. We can also
supply fragrance-containing versions of many of our
products.
Lion
Polymers offers special thermoplastic elastomers
compounds which offer excellent adhesion to selected
substrates. Lionpol thermoplastic elastomers are ideal
for injection molding use in dual-layer applications
(usually referred to as overmolding) or for bonding
layers of dissimilar polymers. This enables otherwise
incompatible polymers to be used together in the same
item.
Lionpol
Thermoplastic Vulcanizates (TPV)
Thermoplastic vulcanizates (TPV) are a special group of
TPE's that contain a crosslinked rubber phase dispersed
within a thermoplastic polymer. Thermoplastic
vulcanizates offer many of the performance features of
crosslinked rubbers, but have the processability of
thermoplastic polymers. Two outstanding benefits of
TPV's are their low compression set and high flexibility.
Another benefit is their very good to excellent solvent
resistance. A significant benefit of Lionpol TPV's is
that scrap from the prime manufacturing process can be
recovered, reground and reprocessed repeatedly without
meaningful decline of final product properties.
For
purposes of properties comparison, thermoplastic
vulcanizates are between olefinic TPE's and urethanes. A
price comparison will show that TPV's are much closer to
olefinic TPE's than they are to urethanes, however.
Lion
Polymers “Lionpol” TPV's are available in Shore A
hardness from 25 to 95 in black or natural and are ideal
for injection molding. Products with greater or lesser hardness
values can be provided if requested. We can supply these
products in pre-colored form or with fillers or
reinforcements if requested.
