Natural Gas and Polymers: Properties, Uses, and Impacts
Natural Gas: Properties, Uses, and Impacts
Natural gas is a mixture of hydrocarbons with a high proportion of methane, often found in oil fields. The methane content in natural gas typically ranges from 75 to 95% of the total volume, hence it’s often called methane gas. Other components include ethane, propane, butane, nitrogen, carbon dioxide, hydrogen sulfide, helium, and argon.
Key Characteristics of Natural Gas
- It is between 35 to 40% lighter than air.
- It is tasteless, colorless, and odorless.
- It
Properties and Types of Composite Materials
Composite Materials: Properties and Applications
1. Composition and Resistance
Key components: Glass, calcium, paste, alumina, silicon carbide, boron carbide.
These ceramics exhibit superior mechanical resistance compared to other ceramic materials. Their low thermal expansion coefficients provide excellent resistance to thermal shock and impact.
2. Early Compounds and Applications
Question: What were the first compounds? What were they used for?
Answer: The initial compounds were combined with fiberglass,

Plastic Materials
Materials: These are materials made of polymers consisting of long chains of molecules containing carbon.
- Natural: Obtained directly from plant materials (pulp) or animals (casein).
- Synthetic or Artificial: Elaborated from compounds derived from petroleum, natural gas, or coal.
Polymerization
Consists of joining small molecules together to form large ones.
Thermoplastic Materials
Compounds obtained from petroleum products. Chains are weakly bound together, soften when heated, and can
