BIOGEAR XP is a range of biodegradable, high performance, extreme pressure (EP) gear lubricants with excellent anti-wear and micropitting performance, available in ISO 68, 100, 150, 220, 320 and 460 viscosities. These lubricants are based on fully saturated synthetic esters with a high degree of renewability and use state-of-the art technology.
BIOGEAR XP is designed for use in sensitive environments where there is a potential for fluid loss to occur, for example from thrusters, some CPP designs and deck equipment.
BIOGEAR XP is miscible with common mineral based gear oils, but in line with good practice, old lubricants should be drained completely to avoid any risk of additive incompatibility and ensure that the full benefits and performance are achieved. Water content should not exceed 0.1% and any free water must be separated off on a regular basis. Unlike the HYDROX range, these lubricants do not emulsify in water.
BIOGEAR XP achieves a biodegradability of greater than 60% in the 28 day OECD 301B test. These products are considered non-toxic in the marine environment based on the following results:
| FISH | DAPHNIA | ALGAE |
| LC50 exceeds 100 mg/l | EC50 exceeds 100 mg/l | EC50 excedes 100 mg/l |
BIOGEAR XP meets the detailed ecological definitions and requirements laid down in the 2013 Vessel General Permit (VGP) published by the US EPA in March 2013.
| Attribute | Benefit |
| Extended fluid life | Fewer fluid changes, less equipment downtime and lower overall cost of ownership |
| Excellent resistance to micropitting | Protects the gear teeth against fatigue wear resulting in less down time |
| High EP protection | Ability to withstand shock and high loads |
| Excellent water separation | Enables easy removal of free water |
| Good hydrolytic stability | Resists breakdown of the lubricant by water in high temperature situations |
| Wider operating temperatures | Protects equipment from -25ºC to over +100ºC |
| Superior oxidative stability | Less sludge and system failures, longer fluid life and less fluid thickening |
| Good elastomer compatibility | Compatible with most sealing materials including Nitrile and Viton |
| Biodegradable and minimally toxic | Lower environmental risk |
