3921N	PVC jacket compound for VDE standard at 90℃	Used for wires and cables which according with VDE standard

II. Productdescription

PVC compound for VDE standard wires andcables, based on PVC resin, is made into granula by mixing, plastification andgranulation with adding plasticizer, stabilizing agent, flame retardant andetc. The products meet various special requirements, such as differenthardness, UV stable, environment friend (RoHs, REACH, PAHs, chlorinated alkanesfree, phthalate free, and etc.),sub-shine and fog surface, low temperature resistant, PS/ABS transfer proof,rodent-repellent, termite-repellent, and transparent, and etc.

III. Processing

It is recommended that compound should beprocessed with common extruder having a minimum L/D ratio of 20.

The following temperature(℃)profile of extruder is recommended:

Zone	Zone 1	Zone 2	Zone 3	Zone 4	Head	Die
Temperature ℃	140	160	170	175	180	175

IV. Storageand transport

Packaging：25kg/bag， PE membrane inside bag and Kraft outsidebag.

Storage and transport: Avoiding in directsunlight and weathering. The storage place should be in clean, cool, dry, andventilated conditions.

Q: Can olive nets be used in combination with weed control methods?: Yes, olive nets can be used in combination with weed control methods. Olive nets are primarily used to protect olive trees from birds and other animals that may damage the fruit. However, they can also act as a barrier to prevent weed growth around the trees. By properly securing the nets to the ground, they can effectively suppress weed growth and minimize the need for additional weed control methods such as herbicides or manual weeding.

Q: What do you mean seven and five under the plastic cup?: Therefore, when the bottle is used up, throw it away and stop using it as a cup. It is best to avoid the heat (as in a car or in the trunk), avoid cracks (release harmful substances); don't try to do storage containers of other items, so as not to cause health problems. "2" - HDPE (HDPE)

Q: How do you know when it's the right time to install olive nets?: The right time to install olive nets typically depends on the stage of olive tree growth and the ripening process. Olive nets are generally installed when the olives have reached their optimal size and color, but before they start falling off the tree due to natural ripening or external factors like wind or birds. Monitoring the olives closely and observing their maturity level is crucial to determine the appropriate time for installing olive nets.

Q: What's the difference between cans and plastic bottles?: Now the cans are coated with internal corrosion layer, is relatively safe, otherwise after the aluminum into the beverage will be adversely affected, aluminum intake too easy to have Alzheimer's disease on the human body; glass bottles generally safer, but be careful with.In contrast, cans are environmentally recyclable products, better than plastics.

Q: What materials are olive nets made from?: Olive nets are typically made from durable and lightweight materials such as high-density polyethylene (HDPE) or monofilament nylon.

Q: Can olive nets be used for both manual and mechanical pruning?: Yes, olive nets can be used for both manual and mechanical pruning. Olive nets serve as a protective barrier to catch the trimmed branches and leaves during pruning, whether it is done manually or with the help of mechanical tools.

Q: Can olive nets be used for olive trees in regions with limited water availability?: Yes, olive nets can be used for olive trees in regions with limited water availability. Olive nets are primarily used to catch falling olives during harvesting, but they can also serve as a protective covering for the trees. By covering the trees with nets, they can help reduce evaporation and water loss from the leaves, thus conserving water in regions with limited availability. Additionally, the nets can provide shade, which can further reduce water evaporation and help maintain soil moisture levels. However, it is important to note that using olive nets alone may not be sufficient to meet the water needs of olive trees in such regions, and other water-saving practices should also be considered.

Q: What is the average cost of an olive net?: The average cost of an olive net can vary depending on the size, material, and quality, but it typically ranges from $50 to $200.

Q: Do olive nets damage the olive tree?: No, olive nets do not damage the olive tree. They are used to protect the olives from birds and other animals, preventing loss or damage to the fruit. The nets are carefully placed over the tree branches and do not cause any harm or negative impact on the tree itself.

Q: Do olive nets require any special training for installation?: No, olive nets do not require any special training for installation. They are simple to set up and can be done by anyone following the instructions provided.
