Markets
Plastics
Plastic compounds can be modified to achieve a wide range of mechanical, processing, visual, and functional properties. Lintech supplies specialty raw materials used in plastics manufacturing and compounding, including materials that support reinforcement, processing, coloration, stabilization, surface properties, flame resistance, and other performance requirements.
Why It Matters
Formulation determines how plastics process and perform
The properties of a plastic article depend on more than the base polymer alone. Fillers, pigments, stabilizers, processing aids, modifiers, and other ingredients can influence stiffness, impact behavior, dimensional stability, appearance, weatherability, flame performance, surface characteristics, and processing behavior.
Material selection is particularly important because changes intended to improve one property can affect others. Increasing stiffness, for example, may influence impact performance or processing, while changes to fillers or pigmentation can affect dispersion, surface appearance, and physical properties. The appropriate balance depends on the polymer, manufacturing process, and intended end use.
Lintech supplies specialty materials for polymer compounding, molding, extrusion, composites, and related plastic applications, providing manufacturers with access to a range of technologies from established raw material suppliers.
