Mediprene® 500584M

ELASTO have developed a range of Mediprene thermoplastic elastomers (TPE) for plunger seals in single-use syringes.

The TPE seal, which is mounted on the end of the plunger, needs to provide a leakproof seal with the syringe barrel. As ease of use for the medical practitioner and patient comfort are also key requirements, the seal helps to optimize plunger movement for accurate dosage control and ease of injection.

Regulatory compliance
Originating from medical raw materials with high biocompatibility status and compounded under clean conditions, Mediprene TPEs are the material of choice for medical customers who want to maximize the probability that their devices will pass relevant medical tests.

The raw materials in these compounds comply with food contact norms like FDA 21CFR and 2011/10 EC. All polymers used have passed tests according to USP class VI and the paraffinic oil has passed the USP Mineral Oil NSF H1, reg 125038 and also the European Pharmacopeia, liquid paraffin.

Mediprene TPEs are latex free, which reduces the risk of allergic reactions. Representative grades have passed cytotoxicity tests according to ISO 10993-5 and biocompatibility tests according to USP Class VI.
