In today's pursuit of sustainable development, the plastics industry faces unprecedented challenges and opportunities. Plastic products are ubiquitous in modern life due to their light weight, durability, and low cost. However, they also pose significant environmental pollution and resource waste issues. To address these challenges, the concept of green chemistry is driving the plastics industry toward a more eco-friendly and sustainable future. The development and application of eco-friendly plastic additives, such as Calcium Acetylacetonate, have become a key driving force in this green revolution.

- In the realm of mechanical engineering, spare parts and oil seals play a pivotal role in ensuring optimal performance and longevity of equipment. These seemingly minor components are the backbone of any machinery's operational efficiency, often going unnoticed until their absence or malfunction is felt.
- Cylinder head gaskets are a vital component of a vehicle's engine, playing a crucial role in maintaining the integrity of the combustion chamber. These gaskets are designed to seal the gap between the engine block and cylinder head, preventing any fluids or gases from escaping or leaking into the combustion chamber.
After the oil seal has been installed, check for leaks. You can do this by applying pressure to the system and observing for any signs of a leak, such as fluid escaping from the area where the oil seal is installed. If a leak is present, you may need to remove the oil seal and start the installation process again.
What are Oil Seals and how should they be ordered?

The material of the sealing lip is chosen according to the liquid to be sealed and the rotational speed. For larger shafts, an NBR sealing lip can cope with surface speeds of up to 10-12 m/s, while an FKM lip is suitable for speeds of up to 35-38 m/s.
WHAT IS THE DIFFERENCE BETWEEN MECHANICAL SEAL AND OIL SEAL?
-80 °C to + 200 °C
Outstanding resistance to mineral oils, aliphatic and aromatic hydrocarbons, as well as CHCs, concentrated and diluted acids, and weak alkalis. Excellent resistance to high temperatures (up to 200 °C) and a low temperature resistance down to -40 °C depending on the type used as well as good mechanical attributes and an exceptionally good ageing resistance make FPM a cut well above the usual synthesis natural rubbers.

When selecting a natural rubber gasket for your specific application, there are several key factors to consider. The first is the hardness of the gasket, which is typically measured on the Shore A scale. A softer gasket (lower Shore A hardness) is more flexible and better suited for applications where the sealing surface is uneven, while a harder gasket (higher Shore A hardness) provides better resistance to compression and extrusion.
This technique involves aligning the installation tool with the face of the shaft to precisely position the seal. Double-checking alignment after installation is essential to avoid future misalignment issues.
These cassette seals are widely used in wheel-end applications, such as the axles of agricultural machinery or off-road trucks.
As shown in Figure 1, sealing devices come in two types: contact and non-contact.
Oil seals are among the major contact type sealing devices.
