中国石油网消息：4月16日，吉林石化生产经营数据显示，该公司自主开发的乙丙橡胶新产品J-3100第一季度销售火爆，实现销量1258吨，创效超200万元，成为该公司新的效益增长点。

China Petroleum Network News: On April 16th, the production and operation data of Jilin Petrochemical showed that the new ethylene-vinyl acetate rubber product J-3100 independently developed by the company achieved strong sales in the first quarter, with a sales volume of 1,258 tons and a profit of over 2 million yuan, becoming a new growth point for the company's profits.

J-3100产品是吉林石化对标进口产品生产的新产品，综合性能优异，具备耐候性、耐臭氧老化性突出等特点，是车用密实条、胶管及模压制品等高端应用场景的理想材料。

The J-3100 product is a new product produced by Jilin Petrochemical Company in line with imported products. It has excellent comprehensive performance and features outstanding resistance to weathering and ozone aging. It is an ideal material for high-end applications such as vehicle dense strips, rubber hoses, and molded products.

目前，国内车用密实条领域被进口产品垄断，年用胶量达到10万吨。该公司乙丙橡胶技术人员近10年来致力于车用密实条用乙丙胶的开发攻关，重点对降低产品气味、改善分子量分布等进行深入研究，多项新技术在2025年7月新建投产的乙丙橡胶D装置得以成功应用。

At present, the domestic market for automotive dense strips is monopolized by imported products, with an annual usage of 100,000 tons of rubber. The technicians of the company's ethylene-vinyl acetate rubber department have been dedicated to the development and research of ethylene-vinyl acetate rubber for automotive dense strips for nearly 10 years. They have focused on in-depth studies on reducing the odor of the product and improving the molecular weight distribution. Several new technologies have been successfully applied in the newly-built ethylene-vinyl acetate rubber D unit, which will be put into operation in July 2025.

新建乙丙橡胶D装置充分融合技术精髓，技术人员有效攻克了干法生产乙丙橡胶中控门尼降解指标、分子量指标不良等行业共性难题，实现了产品气味更低、质量更优的目标。

The newly-built D device for ethylene-propylene rubber fully integrates the core technologies. The technicians have successfully overcome the common industry problems such as the poor control of Miniten degradation index and molecular weight index in the dry process of producing ethylene-propylene rubber, achieving the goal of lower odor and better quality of the product.

在新产品推广阶段，该公司采用“产销研用”一体化协同攻关机制，组建技术服务团队，携样品深入下游推广，解决下游用户试用过程中反馈的拉伸强度、压变和硫化性能等问题。产品质量得到充分认可，达成采购协议。

During the promotion stage of the new product, the company adopted an integrated "production-sales-research-application" collaborative research and development mechanism. It established a technical service team and brought samples to the downstream market for promotion. They addressed the issues such as tensile strength, pressure variation, and vulcanization performance that downstream users reported during the trial use. The product quality was fully recognized and a purchase agreement was reached.
