What is Silica Gel and why do I need it?
Silica Gel adsorbs moisture to create a protective environment of dry air, therefore it is highly effective in preventing moisture damage in enclosed spaces. Silica Gel has been around for over 100 years and is considered the most effective desiccant because it works so well and is so cost effective.
It’s not actually a Gel, rather 2 - 4mm diameter round beads covered in millions of tiny pores that can retain moisture. These beads trap water molecules inside its pores whilst the exterior remains dry.
It can prevent moisture damage such as: rust, mould, corrosion, musty odour, tarnish, oxidation, mildew, fungus, spoilage, spotting and stains.
It is widely used in a variety of industries and markets but its uses are far too extensive to be listed here, check our Top 50 Uses page for common applications and the home page video for a more detailed explanation.
What is our full product range and what are the different types of Silica Gel we provide?
We offer a comprehensive range of Silica Gel sachets, loose Silica Gel in bulk, Moisture Absorbing Boxes, Canisters, Kits, Oxygen Absorbers, Mylar Moisture Barrier Bags, Shipping Container Dry Poles, Clay Desiccant products and Humidity Indicator Cards.
We provide the following types of Silica Gel in permeable sachets or loose bulk: Non-Indicating (White), Indicating (Orange), Part Indicating (Mixed White and Orange)
The Indicating products start to change colour at 60% moisture saturation turning from Orange to Green. The Non-Indicating products are the stock standard White, they do not change colour. Neither of these types of Silica Gel is more effective than the other, the only difference is that the Indicating products provide a visual indication of moisture absorption levels.
Is it safe and environmentally friendly?
Silica Gel is non-toxic, environmentally safe and harmless. We only use organic coatings for the Indicating products. It is the only absorbent approved by the U.S. Food and Drug Administration (USFDA) that is able to be in direct contact with food and medicine.
The “do not eat” warnings printed on the packets are to warn against choking hazards rather than toxic hazards.
How much moisture does Silica Gel absorb?
Silica Gel will adsorb 40% of its own weight in moisture and will continue to work until it has adsorbed that level.
How much do I need?
1 gram of Silica Gel will protect 1 litre of sealed space. Use the calculator to determine what size sachets or Silica Gel quantities are required for your application.
What sachet sizes are available?
The range of Non-Indicating, Indicating and Part Indicating Silica Gel sachets are: 0.5g, 0.75g, 1g, 2g, 3g, 5g, 10g, 20g, 25g, 33g, 35g, 40g, 50g, 100g, 200g, 500g, and 1Kg sachets. The loose bulk options are 675g, 1Kg, 2Kg, 5Kg, 10Kg and 25Kg
How long will it last for and does it expire?
Silica Gel will continue to work until it has adsorbed 40% of its own weight.
How long it will last for depends on many variables such as: moisture sources within the contained space, from the packaging materials and external packaging permeability, how air tight the protection area is, the contents of the protection area, how often the protection area is opened and closed, the relative humidity of the surrounding area, the materials used in the construction of the storage area itself and so on.
What is the packaging it comes in?
Our Silica Gel sachets are packaged in permeable materials that allow air and moisture to pass into the sachets. The sachets are ready to use straight out of the packs.
There are 3 main packaging types:
- Tyvek - a strong, robust polyolefin fibre predominantly used with the larger size sachets.
- Clear Plastic - used for the Indicating Silica Gel products, these are see through so you can see the colour change through the packaging.
- Composite - a non-woven fabric that is commonly used with the smaller sachet sizes.
The loose bulk packs are packaged in 150 micron plastic moisture barrier bags.
Where is Silica Gel commonly used?
Silica Gel is used in various industries and markets. See our Top 50 Uses page for the most common examples of where and how Silica Gel is used.
How can I tell if it needs replacing?
The Indicating products start to change colour at 60% and steadily turn a dark green as saturation levels approach 100%. At that time you will need to replace the Silica Gel as it is fully adsorbed.
The Non-Indicating products do not have any colour change so we recommend including a Humidity Indicator Card in with your Silica Gel sachets to provide a visual guide of saturation levels.
How do I re-use it?
You can re-activate Silica Gel by drying it out in an oven at 70 degrees Celsius for approximately 120 minutes. Speak to us about specific instructions on how this re-activation process is best achieved.
How are the orders dispatched?
How soon after ordering will I receive the goods?
Shipping time commences from receipt of payment for an order. We aim to dispatch orders the day they are received (depending on the time of day the order is received) Typical courier delivery times are within 1-2 days so you should receive your goods in 2-3 days after ordering.

Can we pick up the order instead of delivery?
Being an online retail shop we do not have a physical shop presence and we therefore do not encourage customers picking up their orders in person. However, we do allow pickups for emergencies, contact us to enquire.
What happens with orders that are lost or damaged in transit?
Loss of, or damage to, the purchased item during the delivery process will be covered by the courier companies insurance and their shipping terms and conditions. Their conditions state that they will not cover for goods that are not “track-and-trace” hence, we exclusively use track and trace courier services.
