橡胶工业的环保主要包括两个课题：一是使用环保的原材料，二是降低橡胶工业生产中公害对人与环境的危害。
1 橡胶制品原材料的环保
要求生产出来的橡胶制品不含有超过限定值的有害物质，而且不使用禁用的危险物质，以免危害人体健康，特别是致癌物质。
合成橡胶生产原料中的重金属，加工油，硫化剂，促进剂等在生产过程中都会对环境和人体造成一定的伤害，我们在下面橡胶制品材料对环境的影响里会进行进一步的阐述。
重金属
胶制品原材料的型号、品级都会影响重金属的含量。因此，要注意防止或减量使用含铬和镍的原材料。模具和骨架的镀铬层也会将铬元素带到胶料中来，因此要开发镀铬新技术。胶鞋行业要注意纺织物和皮革染料的重金属限制值，限用含铜、铬、镍的金属络合染料。 橡胶制品中重金属的含量并不只来源于一种或两种重点的原材料，是所有的原材料(包括生胶)重金属含量的总和。有些原材料虽然重金属含量极微，但亦要留意“积少成多〞。
加工油

Per-2~3 measurement, such as proceeds of c values are equal and equal to the design value, then the vertical installation accurate. For example a, b, and c valueswhile on horizontal vertical errors for measurement, General in iron angle code bit at measurement level points grid errors, specific method is from baseline to methyl vertical box center line distance for a,, to b vertical box distance for b, list can measured
