On the one hand, with increasing environmental awareness, the recycling and reuse of waste rubber has become an inevitable trend, and the quality of recycled rubber is directly related to its application in various fields. On the other hand, different rubber products produce different viscosities during use, and the production process also faces different rubber processing requirements.
