Thermoplastic elastomer medical film material

Abstract

The invention provides a thermoplastic elastomer medical film material. The thermoplastic elastomer medical film material is characterized by being manufactured from the following substances in percentage by mass: 30-60% of styrene elastomers, 20-50% of processing oil, 10-40% of plastic, 1-10% of fillers and 1-10% of processing aids. Compared with the traditional medical film material, the thermoplastic elastomer medical film material provided by the invention is novel in material and excellent in performances, has the excellent performances of being capable of being recycled, simple in processing procedures, non-toxic, good in low-temperature resistance, ageing resistance and medicine resistance, wide in hardness range, light in weight, comfortable in hand feel, dry and comfortable, and the like, as well as is favoured by lots of customers.

Description

technical field [0001] The invention relates to the field of medical film materials, in particular to a thermoplastic elastomer medical film material. technical background [0002] At present, most of the medical film materials on the market are polyvinyl chloride (PVC), polyethylene (PP), polyethylene (PE), polyurethane (TPU) and other materials. [0003] However, as we all know, polyvinyl chloride (PVC) has complex processing procedures, poor low temperature resistance and aging resistance, especially in terms of odor and environmental protection, and is less and less used in medical film materials, and even more countries Disabled. [0004] Although polyethylene (PE) or polypropylene (PP) has a wide range of sources, simple processing, and excellent environmental performance, its hardness range is narrow, its hardness is high, its low temperature resistance and elasticity are poor, and it is difficult in terms of hand feeling comfort and elasticity. To meet the needs of...

AI Technical Summary

Problems solved by technology

[0003] However, as we all know, polyvinyl chloride (PVC) has complex processing procedures, poor low temperature resistance and aging resistance, especially in terms of odor and environmental protection, and is less and less used in medical film materials, and even more countries banned

[0004] Although polyethylene (PE) or polypropylene (PP) has a wide range of sources, simple processing, and excellent environmental performance, its hardness range is narrow, its hardness is high, its low temperature resistance and elasticity are poor, and it is difficult in terms of hand feeling comfort and elasticity. To meet the needs of medical film

[0005] In addition, polyurethane (TPU) is easy to hydrolyze, has poor elasticity, poor aging resistance, narrow hardness range, high specific gravity, and limited usability.

[0006] Therefore, in recent years, in order to overcome the defects of the above-mentioned materials, film materials modified with styrene-based elastomers (SBS / SEBS) have sporadically appeared on the market, but due to their odor, hand comfort, high and low temperature resistance, No major breakthroughs have been made in film opening performance and other aspects, resulting in mediocre market response
