Perlite In Pakistan - Wilson Garden

What is Perlite?

Perlite is a naturally occurring volcanic rock that expands to 25 times its original size when heated. Perlite grit is porous with a high surface area which makes it ideal for growing plants indoors or outdoors.

The main role of perlite as a soil conditioner is to add air pockets which allow roots to grow freely without getting “plugged” by other organic matter such as compost or manure pellets. Perlite also helps keep soil loose so that water drains properly away from roots, allowing them to breathe properly.

How is expanded perlite produced?

Perlite ore (natural volcanic glass) is mined from open pit operations or underground mines. Then crush the raw perlite ore into small pieces using crushers or hammers and conveyed into rotary kilns where it is heated to about 1000 °C (1832 °F).

This high temperature melts iron in the rock and changes its structure so that when it cools down again, it expands its volume to more than 700%. Expanded perlite is porous and lightweight, which allows it to provide excellent thermal insulation.

It can also be obtained by leaching certain kinds of clay with a hot alkaline solution until they release their silica content (quartz), which then dries into white perlite balls. Then expanded perlite is cooled and packaged for shipment to customers around the world for use in a variety of applications.

Where to buy perlite Pakistan?

Expanded perlite is made from naturally occurring volcanic glass called obsidian. The obsidian is heated to around 700°C (1,300 °F). This causes it to expand into a lightweight material with millions of tiny air pockets.

Expanded perlite is a porous aggregate added to concrete mixtures to increase strength, reduce shrinkage and provide insulation. You can also use perlite as an insulator in building materials such as fiberglass batts, fiberglass insulation board (IFB), and foam sheathing such as polystyrene.

You can also use perlite as a lightweight aggregate for concrete blocks, block pavers, bricks and paving stones. You can use perlite for gardening in horticulture as an ingredient in potting soil and seed-starting mixes. It is also used as a soil amendment in agriculture.

You can find many expanded perlite suppliers in Pakistan, such as Home Depot etc. You can also purchase perlite at many garden supply stores or online retailers such as Amazon, eBey etc. The perlite price varies depending on the size and weight of the bag you buy.

How to choose expanded perlite Pakistan?

There are several factors that should be considered in choosing the right bulk perlite Pakistan. Expanded perlite should be clean and free of dust and other impurities. It should have a uniform grain size for proper use. If it’s not uniform, it could cause problems in your garden or potting soil.

The moisture content is another important factor to consider when choosing perlite for plants. You need to choose one that is well-moistened so that it doesn’t dry out quickly if you add it to your potting mix or garden soil.

Expanded perlite has excellent insulating properties because its density is low compared with other forms of insulation, making it ideal for use in residential and commercial construction. You can use perlite as an aggregate in masonry mixes or as a lightweight replacement for sand when building forms are required.

Expanded perlite filters out many impurities including bacteria, sediment and organic compounds while allowing water molecules to pass through it freely without clogging up like other filter media such as sand.
