We operate our own quarry, in the central North Island of New Zealand as well as importing perlite ore for specific applications from Turkey, Greece and the USA.

It really couldn’t be easier! Simply open the bag and pour it out. No pre-treating or buffering for pH is needed with perlite of any sort. It makes a fantastic addition to another potting media such as soil or coco, the ratio of which you should be adding depends very much on the media you are adding it to and the system you are going to be using it in. If you think you may benefit from using perlite, but are unsure of exactly how much you should be using, please feel free to give us a ring and one of our experienced staff members will be happy to help. TIPS ON USE Perlite standard is lightweight, density approximately 100kg/m 3. It is supplied in 100 litre bags by Sinclair Professional.Perlite can also be used as part of a 50/50 mix with vermiculite – a very successful mix of media particularly for when rooting cuttings. SwiftAir exfoliated vermiculite and expanded perlite are absorbents and carriers. Each of these unique minerals have their own characteristics. Perlite is widely used in commercial hydroponics, seed starting and plant rooting, as a soil conditioner, and to enhance the water-holding and anti-compaction properties of growing soils. Perlite is a substrate used to improve the physical properties of the soil. It is used to create optimal soil conditions, increase density, reduce drainage and preserve moisture, provide a good breeding ground for seedlings and ensure excellent aeration. Specifically, it is used for agriculture, horticulture, greenhouse cultivation, and sports fields. Expanded perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 5mm in size. It is inorganic, inert, neutral in pH, biologically stable and has no asbestos content. It has excellent thermal insulation properties over an extremely wide temperature range from cryogenics at minus 273°C (absolute zero) up to refractory applications at over 1000°C. It also has a highly adsorbent surface and a very low bulk density, which makes it an ideal carrier or low cost filler for many compound formulations.

Perlite is a white, ultra-lightweight aggregate ranging from a very fine powder to an aggregate with a particle size up to 5mm in size Perlite can be supplied in a number of grades, depending on the particular requirements of the application. As a heat insulation material in industry; Reactors up to 1000° can benefit from Perlite (Standard Grade) insulation. It is an ideal material for cold storages, LPG, LNG, liquid oxygen, liquid nitrogen, ammonia, liquid propane, ethane, methane, liquid noble gases, propellants and refrigerants. Additionally, it makes an effective additive for ceramics and glass production. Non-combustible ultra-lightweight mineral aggregate with excellent insulation & adsorption properties.Perlite is widely utilized in the washing of textiles, particularly denim garments. It imparts a "stonewashed" or "stoned" aesthetic onto clothing items, and facilitates the alteration of surface textures and hues without causing corrosion or clogging of machinery. It is also noted for its lightweight properties which make handling and application easier. If you're looking to get started with hydroponics, don't miss our selection of hydroponic start kits from leading brands and manufacturers. Perlite is used as a standalone growth medium, as well as a way to enhance soil mixes. Made from an amorphous volcanic glass, it has a relatively high water content.

Ideally have a breathing mask when using the product. A lot of fine dust particles will be released into the air when you start pouring it out of the bag. While not immediately life threatening, it’s always best to avoid breathing any of it in. To avoid this spray or wet the perlite slightly before you begin tipping it out of the bag.

Perlite insulation is used in high temperature applications in the steel and foundry industries such as ladle topping, hot topping and risering.

Although Perlite is a fantastic method to increase aeration, because of its porous nature, it does (to a degree) hold on to a certain amount of water simply from the huge surface area that it possesses. If used as a standalone media however, irrigation frequencies need to be dramatically increased, as its water holding capacity is by no means anywhere close to a media like soil or coco. HOW TO USE PERLITE SwiftAir coated expanded perlite is a hydrophobic insulating aggregate. This water repellent, non-flammable, loose-pour insulant improves the thermal performance on masonry walls and floors. Due to its high insulating qualities and versatility expanded perlite is widely used in the construction industry for masonry and other build types. Expanded Perlite is suitable for a range of landscaping applications such as green roof construction, golf green renovation and construction, planters, drainage and reduction.Top Selling Product-Horticultural Perlite Standardgraded for horticultural use, 2.0-5.0mm is used to improve aeration, water management and insulation properties for growing media. In the food industry, Perlite (Standard Grade) 2-5mm is used for straining fruit juices, vegetable edible oils, sugar syrup, corn sherbet (producing glucose I dextrose), beer, wine and liquors. It is also used for filtration of dyes, white water filtration in the paper industry, antibiotics, pectin, citric acid, soda ash solutions, sodium silicate (water glass), sulfuric acid, uranium sherbet, floccine in hydroxide and flocculation processes, as well as phosphoric acid leaching. Additionally, it is suitable for drinking water filtration, swimming pool water filtration, waste water cleaning and filtration processes, and machine oil filtration (regeneration of used machine oils). As a filler i n the p h a r maceut i ca l and chemical i ndust ry; Perlite (Standard Grade) 2-5mm is suitable for many applications, including veterinary and human healthcare drugs, pesticides, cleaning powders, fertilizers, dynamite production and high-performance paint with large surface area coverage. It is also used in the cosmetics industry, such as soaps. Perlite granules have a very porous texture, meaning they are full of micro pores that can store extra amounts of oxygen, vital for you plants to grow healthy and strong! The porous nature of perlite means that water is extremely free-draining though it, meaning less chances of a water-logged pot and over watered plants, when you use it as a growing amendment. It is particularly useful for opening up and aerating dense soils or potting mixes, dramatically increasing the overall available oxygen content. Further to promoting a faster uptake of nutrients, an increased oxygen level will also help to ward off any pathogenic diseases from your pot – helping to keep root rot at bay.
