Swix CH6 blue wax is
for temperature range -6°C to -12°C (21°F to 10°F). CH stands for Hydrocarbon. This category has no fluorocarbon material in the blends. They are 100% high performance hydrocarbon paraffins. Although they can be looked upon as an economical racing wax group, the colder waxes perform very well alone, and the warmer waxes make an acceptable base layer for Cera F. Their colors and temperature ranges coincide with the HF and LF Waxes. The CH waxes can be distinguished from the LF waxes by their darker shade of color.
CH6 wax temperature range -6°C to -12°C (21°F to 10°F). For common cold conditions. Contains also some synthetic wax, which makes it durable in aggressive snow. Good training wax alone. It offers good glide plus base protection at an economical price. Recommended iron temperature setting of 140°C.
Keep in mind, you use a combination of the CH waxes to get the desired temperature range you want. Example: 50% red and 50% yellow wax. You then melt the waxes at the same time on the iron.
