Polymers, Blends and Alloys
Custom medical polymer compounds for minimally invasive devices require precision feeding, melting and dispersion of polymers and additives to achieve a homogeneous blend suitable for applications such as intravascular catheters. All medical polymer compounding is performed on twin screw extruders with processing capabilities suitable for a wide range of base polymers.
| Category | Class | Examples |
|---|---|---|
| Specialty Polymers | Polyolefins | LDPE, HDPE, LLDPE, PP |
| Styrenics | PS, SAN, ABS, HIPS | |
| Vinyls | PVC, EVA | |
| Engineering Polymers | Polyamides | Nylon 6, 6/6, 6/10, 6/12, 11, 12, Amorphous |
| Polyesters | PET, PBT, PETG | |
| Acetals | Copolymer, Homopolymer | |
| Thermoplastic Elastomers | PU, PEBA, COPE | |
| Polycarbonate | ||
| Performance Polymers | High Temperature | PEEK, PES, PPS, PSU, LCP |
| Fluoropolymers | FEP, PVDF, ETFE |
Custom medical polymer compounding may include blending of two commercially available medical polymers to achieve hybrid properties not available from any single resin. Examples include the blending of HDPE and LDPE to achieve intermediate durometers, or nylon and urethane to achieve a balance of lubricity and elasticity. Additionally, medical polymers may be blended with specialized additives for enhanced properties to achieve specific functional requirements.
