Virign Material

HDPE (PE-HD)

  • Semi-crystalline, in its original, undyed state milky/cloudy, matt, and feels waxy
  • A distinction is made between HDPE with loosely connected polymer chains and therefore high density LDPE with tightly connected polymer chains which are therefore of a lower density
    • Craemer products are for the most part made from HDPE, which is supplied in granulate, or pellet, form
  • PE is a thermoplastic material, i.e. malleable within a particular temperature range
  • By cooling and reheating it in its molten state, this procedure can be repeated as often as required
  • The density of HDPE is between 0.94 g/cm³ and 0.97 g/cm³, i.e. it floats in water
    • Craemer plastic pallets and containers made from HDPE have good shape retention at temperatures ranging between -30 °C to +40 °C, briefly up to +90 °C
  • High resistance to acids, alkalis and chemicals and very durable.Weldability Find out more about our expertise in tailor-made plastic pallets

PP

  • Semi-crystalline thermoplasticsThe density of PP is between 0.895 g/cm³ and 0.92 g/cm³3 (plastic with the lowest density)
  • Greater rigidity, hardness, strength and heat resistance than PE
  • It can be heated for a short period to 140° C
  • If the temperature falls far below o° C, the material becomes brittle and friable
  • At room temperature, PP is resistant to almost all common solutions and chemicals
