China C9 thermally polymerized petroleum resin supplier

In the Chinese chemical materials market, C9 thermally polymerized petroleum resin , as an important additive, is widely used in multiple industries, and its suppliers are also facing various questions and concerns from the market. Among them, the issue of whether C9 thermally polymerized petroleum resin is toxic has become an important topic of communication between suppliers and customers. So, how do China C9 thermally polymerized petroleum resin supplier view this issue? Let's learn together.

Carbon nine petroleum resin itself has low toxicity, but may pose health risks under specific conditions. The following provides a detailed analysis from three aspects: its composition, toxicity, and protective recommendations:

1. Composition and Characteristics

C9 thermally polymerized petroleum resin is a thermoplastic oligomer made from C9 fraction, a byproduct of petroleum cracking, through polymerization, distillation and other processes, with a molecular weight range of 300~3000. It has the characteristics of low acid value, good miscibility, water resistance, chemical resistance, and thermal stability, and is often used as a modifier in combination with rubber, coatings, adhesives, and other materials. Carbon nine petroleum resin itself is not a highly toxic substance, and its toxicity mainly comes from trace impurities or incompletely reacted raw materials that may remain during the production process.

2. Toxicity performance

1.Acute toxicity: C9 thermally polymerized petroleum resin has low volatility under normal conditions, and inhaling high concentrations of steam may cause irritation to the eyes, nose, throat, and lungs, leading to symptoms such as headache and dizziness. But this situation is relatively rare and usually occurs when there is a leak during production or storage, and effective protective measures have not been taken.
2.Chronic toxicity: Long term repeated exposure may lead to skin defatting, dryness, itching, and other symptoms. In addition, if C9 thermally polymerized petroleum resin contaminates food or water sources, it may cause toxic reactions and even pose a risk of cancer when ingested by the human body. However, there is currently no conclusive evidence to suggest that C9 thermally polymerized petroleum resin itself is carcinogenic, and its carcinogenic risk mainly comes from possible residual carcinogenic impurities.

3.Environmental toxicity: If C9 thermally polymerized petroleum resin leaks into the environment, it may cause pollution to water bodies, soil, and atmosphere. Its volatile substances may form volatile organic compounds (VOCs), causing persistent pollution to the atmosphere. Meanwhile, C9 thermally polymerized petroleum resin may also corrode organic products in water, such as fishing nets and floats, further exacerbating environmental pollution.

3. Protective suggestions

1.Personal protection: During the production or storage of C9 thermally polymerized petroleum resin, masks containing activated carbon filters should be worn to avoid inhaling high concentrations of steam. At the same time, wear personal protective equipment such as protective clothing and gloves to reduce skin contact.
2.Environmental protection: Strengthen storage and transportation management to prevent leakage. If a leak occurs, immediate measures such as physical adsorption and spraying of chemical reagents should be taken to clean up and reduce environmental pollution.
3.Food protection: Avoid consuming animal, plant, and seafood products contaminated with C9 thermally polymerized petroleum resin. Once ingested, rinse your mouth immediately and observe your physical condition. If there are abnormal or numb sensations in the lips, mouth, or tongue, accompanied by symptoms of headache and dizziness, medical attention should be sought promptly.
Faced with questions about the toxicity of C9 thermally polymerized petroleum resin, China C9 thermally polymerized petroleum resin suppliers have stated that they will strictly comply with relevant national standards and regulations to ensure the safety and compliance of their products. At the same time, they will continue to strengthen technology research and quality control, enhance the environmental performance and added value of their products to meet the needs of the market and customers. In the future, China C9 thermally polymerized petroleum resin supplier will continue to adhere to the safety bottom line, promote the healthy development of the industry, and contribute to the prosperity of the chemical materials market.
