Flooring knowledge

The floor is decided inside the core.

Colour, texture and thickness are only the surface. Inside the board, PVC binds the core, stone powder adds hardness, plasticizer makes PVC softer, and fiberglass is sometimes used to control movement.

Start with Enoch SPC: more PVC binding room and lower stone-powder load. Then ordinary SPC and vinyl become easier to understand.

What Enoch reads

PVC binderStone powderLock edge

01 / Enoch flooring

Enoch flooring starts with a clear SPC formula.

First read the formula. Then the principle becomes easy to understand.

PVC

100 kg

binding strength and toughness

Natural stone powder

250 kg

firmness, weight and structure

PVC: binder, toughness and lock support.

Conclusion

In a balanced SPC formula, more PVC binding room usually means a more stable plank, a stronger click-lock edge and better long-service planning.

Why

Stone powder is only powder by itself. PVC works like the glue that wraps and holds each stone-powder particle together, so the board becomes one complete core.

Result

Stone powder gives hardness. PVC gives bonding strength and toughness. When the lock edge has enough PVC support, it is less likely to chip, crack or lift under normal installation and daily use.

Stone powder: hardness without stickiness.

Conclusion

In a balanced SPC formula, lower stone-powder load usually leaves more bonding strength for the lock, so the floor is less likely to fail at the edge.

Why

Stone powder makes the board heavier, harder and more heat-resistant, but stone powder cannot stick together by itself. It needs PVC to bind it into a plank.

Result

When stone powder is kept in a workable balance, the board can stay firm without becoming dry and brittle at the thin tongue-and-groove profile.

02 / Ordinary SPC flooring

Ordinary SPC can be hard in the sample, weaker at the lock.

The issue is not the SPC name. The issue is how much stone powder the PVC has to bind.

PVC

100 kg

the same binder has to hold more powder

Natural stone powder

350-450 kg

hardness, weight and lower material cost

PVC: the same binder has to hold more powder.

Formula

A low-cost ordinary SPC route may still use PVC 100 kg, but raise stone powder to 350-450 kg.

Why

The same PVC now has to wrap much more mineral powder. If the binder is stretched too far, the board can feel hard but lose toughness where the lock is thin.

Result

The click-lock edge becomes easier to chip, crack, loosen or lift, especially during cutting, tapping, uneven subfloor pressure, furniture load and daily movement.

Stone powder: lower cost, higher brittleness risk.

Conclusion

More stone powder can reduce material cost, but it does not automatically make a better floor.

Why

Stone powder has no stickiness. When it becomes too high, PVC has less room to wrap and bind the core, so the board can turn hard, dry and brittle.

Result

In weak low-cost routes, visible problems can start within months to under two years: lock cracks, open joints, raised edges, movement, noise, bulging or early replacement pressure.

03 / Vinyl flooring

Vinyl flooring starts soft because the formula is softened.

Read the possible problems first, then the material reason. Vinyl is not judged by soft feel alone.

PVC

100 kg

naturally a rigid plastic phase

Stone powder

400-500 kg

hardness, weight and heat resistance support

Plasticizer

30-40 kg

softens PVC into flexible vinyl

Fiberglass

reinforcement

helps control movement in a softened floor

Possible floor problems first.

What can happen

A softened vinyl floor can open small gaps, curl, indent, move, lose grip at the click-lock edge, or feel less stable under heat, sunlight, heavy furniture and repeated walking.

Why

PVC itself is a rigid plastic phase. Vinyl becomes soft because the formula is softened, so the floor depends on a softener route instead of a tougher rigid SPC core.

Plasticizer: soft feel needs proof.

Formula role

Plasticizer is added to make PVC softer and more flexible. The more plasticizer the floor uses, the softer the material route becomes.

Floor risk

When the core is softer and less heat-resistant, click-lock flooring can separate more easily, because the lock depends on enough stiffness to stay engaged.

Exposure path

Heat can increase the chance of plasticizer migration, odor or residue exposure, so Enoch needs the exact softener name and documents before treating vinyl as a long-term indoor option.

Why this matters for people, babies and pets.

Exposure path

Floors are large indoor surfaces. Adults walk on them, babies touch them, and pets lie close to them. The practical routes are indoor dust, hand-to-mouth contact, skin contact, pet licking, cutting dust and long indoor time.

Boundary

This is not a medical claim. It is the reason Enoch asks for material documents instead of accepting the word soft, eco or vinyl as proof.

Why fiberglass is added, and why it needs care.

Why it appears

Vinyl can become less dimensionally stable because it is softened. Fiberglass can be added to help control expansion and shrinkage.

Handling risk

Cutting, damaged edges, repairs and removal can create fine dust or fibers. Enoch looks for a clear cutting, cleanup and disposal method before treating the system as suitable for an occupied home with children or pets.

Final comparison

Enoch SPC, ordinary SPC and vinyl are three different material formulas.

Formula

Enoch SPC

PVC 100 kg + stone powder 250 kg

Ordinary SPC

PVC 100 kg + stone powder 350-450 kg

Vinyl flooring

PVC 100 kg + stone powder 400-500 kg + plasticizer 30-40 kg + fiberglass

Core logic

Enoch SPC

PVC has more room to bind the stone powder into a tougher plank.

Ordinary SPC

The same PVC has to bind more powder, so the core can become harder but more brittle.

Vinyl flooring

Plasticizer softens PVC, while fiberglass tries to control the movement created by softness.

Lock behavior

Enoch SPC

The lock edge is supported by a tougher rigid-core balance.

Ordinary SPC

The thin lock edge can chip or crack when the core is dry and brittle.

Vinyl flooring

The softened formula can increase gap, movement and disengagement risk if documents and use conditions are weak.

Long-term view

Enoch SPC

Suitable for 10+ year planning when site condition, installation and use fit.

Ordinary SPC

Weak low-cost formulas can become short-life flooring under stress.

Vinyl flooring

Needs clearer proof because softness, plasticizer use and fiberglass handling affect the long-term result.

Enoch verdict

Enoch SPC

Ordinary SPC

Do not judge by SPC name, hardness or weight alone.

Vinyl flooring

Do not treat soft feel as proof of comfort, safety or durability.
