介绍PVC树脂，即聚氯乙烯树脂，是一种重要的有机合成材料。PVC树脂是一种极性非结晶性高聚物，分子间作用力较大，性质硬脆，抗冲击强度较低。​​其化学结构式为(CH₂-CHCl)ₙ。通常为白色粉末，无毒无味。聚氯乙烯 (PVC) 由氯乙烯单体 (VCM) 聚合而成。聚合工艺主要有两种：悬浮法聚氯乙烯 (PVC) 和乳液法聚氯乙烯 (PVC)。聚氯乙烯是继聚乙烯和聚丙烯之后，全球产量第三大的合成塑料聚合物。用聚氯乙烯树脂制成的产品具有良好的物理和化学性能。它耐用、轻便、坚固、防火，并具有优异的绝缘性能和低渗透性。聚氯乙烯广泛应用于工业、建筑、农业、日常生活、包装、电力和公共事业等各个领域。在建筑行业，它用于制造管道、窗户、门等；在医疗保健行业，它用于制造血袋和导管；在电子行业，它用于电线电缆的绝缘。

Introduction Selected from naturally sun-ripened red tomatoes grown in the open fields of Xinjiang's Gobi Desert, this pure tomato paste is made by peeling and deseeding fresh tomatoes, then low-temperature vacuum-concentrating them. Free from sucrose, vinegar, and artificial preservatives, it differs from table condiments and serves as a professional-grade concentrated tomato base for restaurants and food manufacturing facilities. Seven to ten pounds of fresh tomatoes are condensed into one pound of paste—deep red with a glossy sheen, smooth and thick in texture, offering a balanced natural sweetness and acidity with rich, authentic tomato aroma. High in lycopene, it is a universally used foundational ingredient in Chinese, Western, Middle Eastern, and African cuisines worldwide.

Introduction Non-Dairy Creamer (commonly known as milk powder) is made from plant oils, glucose syrup, and emulsifiers. It is processed through emulsification, homogenization, and spray drying to form powder ingredients. Its main features are whitening and enhancing the smoothness of milk flavor. It is widely used in milk teas, instant coffee, baking, solid cereal, and ready-made soup mixes. Customized low-fat / medium-fat / high-fat and trans-fat-free formulas are available. The factory directly supplies bulk exports and OEM production for domestic food factories.
