GLASS BOTTLE WITH PU COVER SILICA

Product Description

• Core Material: Glass (often Borosilicate or Silica Glass)
  • Glass: Provides a clean, non-reactive, and odor-free way to store beverages. It's often preferred for taste purity and health reasons as it doesn't leach chemicals.
  • Borosilicate Glass: This is a common type of glass used for these bottles because it's known for its high resistance to thermal shock (can withstand hot and cold liquids without cracking easily) and its lighter weight compared to traditional soda-lime glass.
  • "Silica Glass Bottle": The term "Silica" here refers to the primary component of glass, silicon dioxide (silica). While all glass is made of silica, sometimes this term is used to emphasize the high-quality or pure nature of the glass, implying it's clear and durable.
• Protective Cover: PU (Polyurethane) or Silicone Sleeve
  • The "PU cover" (Polyurethane) is a key feature. It's a synthetic leather-like material or a durable plastic polymer that forms a sleeve around the glass bottle.
  • Purpose of the Cover:
    • Protection: Significantly reduces the risk of breakage if the bottle is dropped, making the glass bottle more suitable for daily carry and outdoor activities.
    • Grip: Provides a non-slip surface, making the bottle easier and more comfortable to hold, especially when the bottle is wet or cold.
    • Insulation (Minor): Offers a slight degree of insulation, helping to maintain the temperature of the contents, though not as effectively as vacuum-insulated stainless steel bottles.
    • Aesthetics: Adds a stylish and often sleek or rugged appearance to the bottle, coming in various colors and textures.
  • Sometimes confused with "Silicone Cover": While the user specified "PU cover Silica," it's worth noting that silicone sleeves are also very common for glass bottles for similar protective and grip purposes.
