Formula: PS - X - Linked
Form: Rod
Material: Polystyrene (PS) - Cross-linked
CAS Number: 9003-53-6
Commodity: Polymers
Introducing our Polystyrene Cross-linked Rods that contains 103 variations of cross-linked polystyrene, a rigid thermoplastic polymer. This provides improved temperature and solvent resistance compared to standard polystyrene. These rods offer high stiffness and dimensional stability making them ideal for applications like scientific instrumentation components, spacers and modeling. Thanks to our range including different diameters and lengths, Polystyrene Cross-Linked Polystyrene rods offer researchers and engineers an extensive selection of this versatile engineering thermoplastic.
