Embodiment Construction

[0039] A polymer elastomer material for balloon catheter medical devices, which is made of the following raw materials in weight percentage:

[0040] SEBS I 0-70% (eg 5%, 35%, 70%)

[0041] SEBS II 0-80% (eg 5%, 35%, 80%)

[0042] Medical grade polypropylene 5-20% (eg 5%, 10%, 20%)

[0043] Polyolefin elastomer 5-25% (eg 5%, 15%, 25%)

[0044] Medical grade filler oil 0-30% (eg 1%, 15%, 30%)

[0045] Antioxidant 0.1-1% (eg 0.1%, 0.5%, 1%)

[0046] Other additives 0-1% (eg 0.1%, 0.5%, 1%);

[0047] The sum of the amounts of the above-mentioned components is 100%.

[0048] The SEBS I is a saturated styrene-butadiene-styrene block copolymer.

[0049] Said SEBS II is a special SEBS with more 1,2 polymerization components in its rubber chain, that is, more vinyl side chains, such as Kraton ERS (Enhanced Rubber Segment) SEBS G1645.

[0050] The polypropylene is a food-grade copolymerized polypropylene with a melt index of 20-40g / min.

[0051] The polyolefin elastomer materia...

Abstract

The invention discloses a high polymer elastomer material for balloon catheter type medical apparatuses and instruments and a preparation method thereof. The product comprises SEBS (Styrene Ethylene Butadiene) I, SEBS II, medical-grade polypropylene, a polyolefin elastomer, medical-grade extending oil, an antioxidant and other auxiliaries. The material disclosed by the invention has high tensile strength, excellent rebound resilience, high and low temperature resistance, high transparency, non-toxicity, excellent biocompatibility and blood compatibility and no anaphylactic reaction with a human body, and is easy to process. Besides, the production technology is advanced, the process is reasonable and simplified, the investment scale is small, the energy consumption is low, the production efficiency is high, and the preparation method is safe and environment-friendly.

Description

technical field [0001] The invention relates to a polymer elastic body material for balloon catheter medical devices and a preparation method thereof. Background technique [0002] Traditional in vivo medical devices are made of natural rubber, latex, and silica gel. Although they have been used in clinical practice for many years, patients are allergic and materials crack in clinical practice. The production is complicated and difficult to recycle, causing environmental pollution. [0003] Thermoplastic elastomer (TPE) is a kind of polymer material that exhibits rubber elasticity at room temperature and can be plasticized at high temperature. It has the characteristics of both rubber and thermoplastics. Its polymer segment consists of a plastic segment (hard segment) and a rubber segment (elastic soft segment). It has the characteristics of vulcanized rubber at room temperature and the processing characteristics of thermoplastics at high temperature. [0004] Compared wit...
