锦纶纤维是世界上出现的第一种合成纤维，其主要品种有锦纶 6 和 锦纶 66。凭借轻便、耐极低温、优异的弹性恢复力、更好耐磨性、染色性能和吸湿性等优势，其作为升级面料在民用领域被广泛应用于运动衣、羽绒服、户外运动服、时尚休闲服等。PA6 与 PA66 性能有差异，将长期共存互为补充。

2024 年 6 月份中信基础化工行业指数下跌 8.68%，在 30 个中信一级行业中排名第 21 位。子行业中，合成树脂、钾肥和氟化工行业表现相对较好。主要产品中，6 月份化工品整体延续回调，涨跌比较上月下降。上涨品种中，丁醛、异丁醇、新戊二醇、丁二烯和硫酸涨幅居前。7 月份的投资策略，建议三条主线布局，关注煤化工、轻烃化 工、磷化工和涤纶长丝行业。

应用广泛的基础化工原料。纯碱是一种重要的基础化工原料，生产 的主要原料包括原盐、合成氨、石灰石等。纯碱下游应用领域包括平板玻璃、日用玻璃、光伏玻璃、小苏打、硅酸盐、碳酸锂等行业。纯碱工业产品主要包含轻质纯碱和重质纯碱两种，这两种产品的化学性质无区别，只是物理性质有所不同。轻质纯碱主要用于冶金、造纸和印染等工业，重质纯碱主要应用于平板玻璃、玻璃制品、洗涤剂和陶瓷釉等的生产。

截至 5 月 31 日，化工行业指数/CCPI/氟化工指数分别报 3337.67/4836.00/1266.88 点，分别较 4 月末-1.46%/+2.85%/-6.84%。5 月氟化工行业指数跑输申万化工指数 5.34%、跑输沪深 300 指数 6.16%。国信化工氟化工价格指数/制冷剂价格指数分别报 1103.23/1357.60 点，分别较 4 月底+2.0%/+4.5%。截至 6 月 3 日，R22 内贸市场因售后维修需求带动且 2024 年配额削减预期，价格持续强势，出口需求向好、内外价差修复。

Dimethyl ether is sourced from different resources such as natural gas, coal, and bio-based products. The expanding research for dimethyl ether as an alternative fuel option will likely create lucrative opportunities for the market during the forecast period. After the easing of lockdowns, the LPG fuel blending industry picked up, and the demand has risen globally. Global countries such as China, India, South Africa, Brazil, and Germany are aggressively shifting to use dimethyl ether as an alternate fuel, as these countries are highly dependent on imports to fulfill their local LPG demand. The growing demand for the LPG blending application is expected to propel the market's growth. However, the heightened costs of changing the current infrastructure to use dimethyl ether may restrain market growth. Thus, the demand for alternative fuel options such as dimethyl ether-based products in LPG blending industries is offering immense growth potential to the dimethyl ether market over the forecast period.
