BARINTHUS PT-E 460/2high-temperature synthetic grease oil, with PTFE additive, offers durability and long-lasting lubrication in heavy industry conditions.

BARINTHUS PT-E 460/2 | PTFE Additive High-Performance Synthetic Temperature Grease

BARINTHUS PT-E 460/2, specially developed for high-temperature operating systems, is a synthetic temperature grease with a PTFE additive. It maintains its stability in a wide temperature range of -40°C to +260°C, ensuring long-lasting lubrication and hardware protection even in challenging environments.

This high-performance grease is safely preferred in heavy industrial sectors such as iron-steel, cement, ceramics, paper, and plastics production lines. PTFE reinforcement reduces friction, minimizes wear, and the low evaporation characteristic ensures long-term lubrication performance.

Offering high resistance to water, chemicals, and corrosion, BARINTHUS PT-E 460/2 is also free of toxic contents with its eco-friendly formula. Its compatible nature with automatic and manual lubrication systems provides user application flexibility.

Advantages:

• PTFE additive providing top-level resistance against wear

• Wide temperature range: -40°C to +260°C

• Water and chemical resistant formula

• Low evaporation – maintaining high performance even at high temperatures

• Compatible with automatic lubrication systems

• Free of chlorine, lead, baryum – eco-friendly

• Long service life under high load

• Superior adhesion and film continuity on metal surfaces

Application Areas:

• Bearings operating at high temperatures in iron-steel and cement factories

• Kiln cars and dryer cylinders in the ceramic sector

• Calenders and film rolling machines in plastic production

• Steam rollers and motor bearings in textile machines

• Industrial gearboxes and vehicle wheel bearings

These products, replacing the RESTOREPLUS BARINTHUS PT-E 460/2 product in the market, are designed for industrial applications where heavy loads, high temperatures, and chemical aggressiveness are at peak levels. They are counterparts in the ultra-premium greases class with high-viscosity PFPE base oil and PTFE thickener:

Equivalent Brands and Products

BARINTHUS PT-E 460/2, unlike other products in the series, has a higher base oil viscosity (ISO VG 460), making it suitable especially for low-speed but extremely heavy-loaded kiln bearings. The main counterparts in the market are:

• RESTOREPLUS: Barinthus PT-E 460/2

• MOLYKOTE: HP-870 (Heavy Duty Series) / HP-300

• KLÜBER: Barrierta L 55/2 (High Viscosity Class) / Klübertemp HM 83-402

Technical Information and Properties

Based on Restoreplus Barinthus PT-E 460/2, the common technical values possessed by alternative products in this segment are as follows:

• Technology: Manufactured with a combination of High Viscosity PFPE (Perfluoropolyether) base oil and PTFE (Teflon) thickening agent that provides an oil film that does not break even under the heaviest load conditions.

• Type: It is of the structure of a Heavy Duty Type Ultra High-Temperature Grease, which is chemically completely inert, non-flammable, and has an evaporation rate that is almost zero.

• Operating Temperature: Offers extreme thermal endurance, maintaining its physical and chemical structure within the range of -30°C to +280°C (peaking at +300°C) without leaking or coking.

• Load Carrying Capacity: Thanks to the ISO VG 460 viscosity class base oil, it forms a Thick Oil Film between surfaces even at low speeds. This maximizes the service life of large bearings under heavy loads.

• Chemical Resistance: It does not React even when in contact with oxygen, chlorine, strong acids, and solvents. It is the most reliable class for sealing and lubrication in chemical and petrochemical facilities.

• Long Life: Its oxidation stability is so high that it can lubricate for the Bearing's Life Time (fill-for-life) under suitable sealing conditions, radically reducing maintenance costs.

• Compatibility: Does not interact adversely with any plastic, elastomer, or metal alloy. It protects the Sealing Elements (Seals) and prevents them from hardening.

• Consistency: Belongs to NLGI 2 class, which maintains stable behavior and does not lose its sealing feature in high-temperature heavy-duty bearings.

Application Area: This product is particularly used in corrugated cardboard production roll bearings, heavy-duty chains of textile industry stenter ovens, high-temperature kiln carriage bearings in the cement and glass industry, and in chemical valve systems.
