Polyurethane BandPolyurethane Bands, which are made of soft plastic, may turn hard after 2-3 year's use. Colour fading can also be seen.
If bands are kept wet and in highly humid locations or are exposed to sunlight for a long time, the deterioration of the bands may be accelerated in a relatively short period and some cracks may appear on the band surface. (This is called 'hydrolytic cleavage of polyurethane')
Kindly pay attention to the condition of polyurethane bands, which are often worn in such occasions as marine sports/outdoor activities
- We recommend immediate exchange when your polyurethane band loses elasticity or develops cracks.
- Semi-transparent/white/fair coloured polyurethane band may turn a different colour due to light/stain ( or sometimes may absorb colours from other materials). In addition, polyurethane bands have many small holes on the surface, which easily catch and hold stains/other different colour material. Thus it is rather tough to entirely clean polyurethane bands. Kindly replace current polyurethane band with a new one when you find extreme discolouration.
- There exist some sorts of stains (like oil/cosmetics), which cannot be removed off. Smoking cigarette/long time use may turn the colour yellowish.
CAUTION!
Do not use solvent/chemicals (benzene/thinner/breach) for band/bracelet cleaning!
