制作硅胶牙刷的牙刷硅胶其实是医用硅胶。我们前面讲了很多关于生活中的硅胶，硅胶已经慢慢的要普及了。硅胶应用在各种不同的领域。在超市买了把牙刷手感很好，仔细看下说明是医用硅胶牙刷。
硅胶的优异的特性有应用到了现实的产品当中。硅胶牙刷是由刷柄和刷头两部分组成。刷柄材料：PP+TPU/TPR 刷头材料：100%医用硅胶刷柄耐热范围：≤100℃刷头耐热范围：≤260℃消毒方式：蒸、煮消毒执行标准。这里体现出了硅胶的耐高温、无色无味无毒等深圳市红叶杰科技有限公司。
根据硅胶的特性映射出产品优点如下： 1、刷头材料具有优异的生理惰性与化学惰性，不氧化，不降解，不变形。2、刷毛柔软、刷牙时不伤牙龈及牙釉质，无牙龈出血现象不伤釉质。3、按摩牙龈，促进牙龈组织血液循环，预防牙周病、牙龈萎缩。4、硅胶无毒、无味，不沾水其吸水性小于0.015%，高透气性，细菌无孳生。5、刷头具有耐高温性能，≤260℃高温蒸煮消毒）高温消毒。6、刷头采用医用硅胶制作而成，柔软、磨擦系数小，使用寿命长。
硅胶模具是快速模具里的一种最为简单的方法，一般是用硅胶将原型进行复模，但寿命很短，只有20件左右。它具有很好的弹性和复制性能，用硅橡胶复制模不会影响尺寸精度，有很好的分割性，不用分上下模，可直接进行浇注。 再沿预定的分模线切割取出母模就可以了。 室温硫化硅橡胶又分为加成型和缩合型两种。
采用专用硅橡胶模具，该品系以双包装形式出售，A组是胶料，B组是催化剂。配制时要考虑室温、模具的强度和硬度，以此来确定AB组的重量配制比例。室温在20—25度时，A：B=100：1.5。室低时适当增加B组份0.1—0.3份。室温偏高则减少B组0.1—0.3份。具体方法是据硅胶模具体积确定总用量，然后将A、B组份按比例称量准确，置于器皿中搅拌均匀即成。
制模：将调配好的材料，倒入待仿制的清洁的实物上即可。为了节省材料，制得较薄的硅胶制品模具，也可分次涂刷。为增加模具的拉力可糊纱布之类。在室温20度条件下2小时就能化为弹性体，一天后就可使用
