PU Polyurethane Injection Molding Products Rubber Buffer Blocks High Elasticity
Little knowledge of polyurethane and polyurethane rubber properties
Polyurethane is polymerized by polyester (or polyether) and diisocyanate compounds. It has good abrasion
resistance, followed by good elasticity, high hardness, oil resistance, and solvent resistance.
Polyurethane is a very special polymer. It is composed of hard segment and soft segment. The hard segment
has a low TG and has the characteristics of plastic. The soft segment TG is much higher than room temperature
and has the characteristics of rubber. It is used in the synthesis process of polyurethane. Among them, by
controlling the polymer reaction, the ratio of the hard segment and the soft segment of the polymer can be
adjusted, so that the polyurethane is mostly plastic or rubber.

Our injection molding operation is optimized for producing high-quality, complex products.
Our injection molding works are optimized to produce complex, high-quality products.
What makes a product complex? Your product can be complex if necessary: attachment insert, injection molded
material, large product size and / or both thick and thin cross-sectional areas. We also make various sizes of
injection molding machines to accept very small product sizes.
Injection molding is a repetitive process with a fast cycle time on the order of seconds. The entire
process takes place in one specialized, automated injection molding machine. It starts with
feeding solid polyurethane pellets into the machine's injecting barrel. The barrel contains a
reciprocating screw that pushes the pellets forward toward the mold. The high shear action of
the screw frictionally heats the pellets, fully melting them by the end of the barrel. When enough
material has accumulated at the end of the barrel, the molten polyurethane is forced at high
pressure and velocity into the mold in one shot.
Our thermoplastic polyurethanes cover a wide range of performance properties.
We customize the formulation of our polyurethanes to meet the specific
requirements of each project. Tell us about your application and we’ll guide you
through your best material options.
