What is cas number 64742 478?

What is cas number 64742 478?

High Flash Point Solvent | CAS-No. 64742-47-8. LPA® 170 Solvent is a high-purity mixture of hydrotreated isoparaffins and naphthenics with very low levels of polynuclear aromatics. It is an excellent process solvent with high flash point and narrow boiling range.

What are distillates petroleum hydrotreated light?

“Hydrotreated light distillates (petroleum)” are a complex mixture of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst. These substances consist of aromatic-free C6–C13 hydrocarbons with a distillation range of 65°C to 230°C.

What is hydrotreated heavy naphthenic?

What are Distillates (petroleum), hydrotreated heavy naphthenic? They are high quality naphthenic base oils with a low pour point and good solvency properties. They have been extensively hydrotreated resulting in low aromatic, clear, bright and less coloured mineral oil with excellent stability.

What are petroleum distillates used for?

Petroleum distillates are good for removal of heavy oil and grease, tar, and waxes. The low surface tension of many of these solvents allows them to penetrate and clean small spaces. They are flammable, so they are usually used at or near room temperature. They are typically used in immersion or hand-wipe processes.

Are petroleum distillates harmful?

-Skin disease: Petroleum distillates are skin defatting agents and can cause dermatitis on prolonged exposure. They may also cause irritation of the eyes, throat, and skin. 2. Long-term Exposure: Prolonged overexposure may cause drying and cracking of the skin.

How do you make light distillate from petroleum?

Petroleum distillates, hydrotreated light are a complex mixture of hydrocarbons ob- tained by treating a petroleum fraction with hydrogen in the presence of a catalyst. This mixture consists of hydrocarbons with carbon numbers predominantly be- tween C9 and C16 and with boiling points approx.

What is hydrotreated heavy?

Hydrotreated heavy naphtha (petroleum) is a complex mixture of hydrocarbons ob- tained by treating a mineral oil fraction with hydrogen in the presence of a catalyst. According to the definition of the CAS number, it is a mixture free of aromatic hydrocarbons (ACCOP 2001, 2004).

What is severely hydrotreated heavy naphthenic oil?

Definition: A complex combination of hydrocarbons obtained by treating a petroleum fraction with hydrogen in the presence of a catalyst.

Is petroleum toxic to humans?

Adverse health effects can include skin irritation, eye irritation, dizziness, headache, nausea and, and in extreme cases, death (2). Because petroleum is widely used, unintentional acute releases can occur almost anywhere.

What happens if you inhale petroleum distillates?

exposure may cause bronchitis to develop with coughing, phlegm, and/or shortness of breath. ► Petroleum Distillates may affect the liver and kidneys.

How big is the molecular weight of Desmophen?

Desmophen® products are a versatile family of polyether polyols, which includes diols, triols and polymer polyols with molecular weights that vary from less than 300 to as much as 6,000 g/mol.

What can Desmophen diols be used for?

Desmophen® products are a versatile family of polyether polyols, which includes diols, triols and polymer polyols with molecular weights that vary from less than 300 to as much as 6,000 g/mol. They are used as polyol components for polyurethane and polyurea formulations. When reacted with Desmodur® products from Covestro,…

Are there any polyurethanes based on Desmophen?

Polyurethanes based on Desmophen® polyols, particularly when reacted with Desmodur® crosslinkers, are also fast-drying, durable and elastic, with an excellent resistance to chemicals, weathering and UV radiation. Get in touch with us to develop a unique formulation for your specific needs.

How is Desmophen used in the foam industry?

It is specifically designed for the production of conventional flexible slabstock foams with enhanced loadbearing properties, using CO2-technologies due to its appropiate particle size distribution. It exhibits a broad processing range and allows the use of most commercially available silicone surfactants and tertiary amine catalysts.
