Freshwater algae show low-to-moderate susceptibility to TiO2 exposure, with more pronounced toxic effects in the presence of UV irradiation. It has also been shown that nano-sized TiO2 is significantly more toxic to algae Pseudokirchneriella sub-capitata than submicron-sized TiO2. Hund-Rinke and Simon  reported that UV irradiated 25 nm TiO2 NPs are more toxic to green freshwater algae Desmodesmus subspicatus than UV irradiated 50 nm particles, which is in agreement with Hartmann et al. UV irradiated TiO2 NPs also inactivated other algae species such as AnabaenaMicrocystisMelsoira and Chroococcus. It was demonstrated that smaller particles have a greater potential to penetrate the cell interior than submicron-sized particles and larger aggregates. Studies have shown that the amount of TiO2 adsorbed on algal cells can be up to 2.3 times their own weight.

  • Self-vulcanizing rubber, also known as self-amalgamating rubber, incorporates the curing agents within its matrix. Upon exposure to air or moisture, these agents activate, initiating the vulcanization process without the need for external energy sources like heat or radiation. The result is a highly efficient and eco-friendly material that cures at room temperature, significantly reducing production costs and energy consumption.
  • Tape offers an extensive line of single coated film tapes with a variety of film backings and adhesive systems.  Our polyester-silicone tapes are used for splicing silicone coated papers and high temperature masking applications.  We offer these in different colors and different thickness’ depending on your application needs.   We also offer polyester-acrylic tapes, polyimide-silicone, polyester-acrylic and polyethylene-rubber.

  • What is Automotive Wire Wrap Tape?
  • Strip seals are also widely used in industrial equipment, HVAC systems, and household appliances. These seals help to maintain the efficiency and functionality of equipment by preventing leaks and contamination. In HVAC systems, strip seals ensure proper insulation and airflow, improving energy efficiency and comfort. In household appliances such as refrigerators and ovens, strip seals help to maintain the desired temperature and prevent food spoilage.
  • One of the key advantages of flame-resistant tape is its ability to maintain its structural integrity at high temperatures. This means that even if a fire breaks out near the taped area, it will not easily melt or burn through, providing an additional layer of protection. Additionally, these tapes are often coated with a fire-retardant chemical that helps to slow down the spread of flames and reduce the risk of ignition Additionally, these tapes are often coated with a fire-retardant chemical that helps to slow down the spread of flames and reduce the risk of ignition Additionally, these tapes are often coated with a fire-retardant chemical that helps to slow down the spread of flames and reduce the risk of ignition Additionally, these tapes are often coated with a fire-retardant chemical that helps to slow down the spread of flames and reduce the risk of ignitionflame resistant tape.
  • The installation process of rubber strips is straightforward and often involves peel-and-stick applications, making it a DIY-friendly project for homeownersdoor seal with rubber strip. The flexibility of the material allows it to adapt to various door frames, ensuring a snug fit that does not compromise door operation. Moreover, rubber strips come in different sizes and thicknesses, allowing homeowners to choose the option that best fits their specific needs and aesthetic preferences.
