Medium temperature asphalt block
Indicator requirements:
Softening point: 50-70 ℃
ash content: ≤ 0.5%.
Product features and uses: This type of asphalt has a low softening point and is generally used for blending oil in coking goods. Low temperature asphalt belongs to special asphalt and can also be used for asphalt paint, recycled rubber, rubber products, waterproof materials, anti-corrosion, paving, etc. Our factory can produce according to customer demand indicators.
Soft Pitch is the residue of tar distillation, with a yield of 54-56% of tar. It is composed of aromatic compounds with more than three rings, oxygen-containing, nitrogen-containing, sulfur-containing heterocyclic compounds, and a small amount of high molecular weight carbon substances. The molecular weight of asphalt components ranges from 200 to 2000, with a maximum of 3000. Medium temperature asphalt is classified based on different softening points. The softening point is 60-80 ℃ for medium temperature asphalt.
