Our products contain Polypropylene material which is known as sensitive to low temperature. The useful temperature for regular PP grades is between +5ºC (+41ºF) to 60 ºC (+1 40 ºF). At this range of temperatures the products have good resistance to shock and impact and keep their shape and toughness. Our products can be stored at lower temperature, and their characteristics return when the temperature goes back to a room temperature.
